32 | /* Understanding this module means understanding the interface between | |
33 | the g77 front end and the gcc back end (or, perhaps, some other | |
34 | back end). In here are the functions called by the front end proper | |
35 | to notify whatever back end is in place about certain things, and | |
36 | also the back-end-specific functions. It's a bear to deal with, so | |
37 | lately I've been trying to simplify things, especially with regard | |
38 | to the gcc-back-end-specific stuff. | |
39 | ||
40 | Building expressions generally seems quite easy, but building decls | |
41 | has been challenging and is undergoing revision. gcc has several | |
42 | kinds of decls: | |
43 | ||
44 | TYPE_DECL -- a type (int, float, struct, function, etc.) | |
45 | CONST_DECL -- a constant of some type other than function | |
46 | LABEL_DECL -- a variable or a constant? | |
47 | PARM_DECL -- an argument to a function (a variable that is a dummy) | |
48 | RESULT_DECL -- the return value of a function (a variable) | |
49 | VAR_DECL -- other variable (can hold a ptr-to-function, struct, int, etc.) | |
50 | FUNCTION_DECL -- a function (either the actual function or an extern ref) | |
51 | FIELD_DECL -- a field in a struct or union (goes into types) | |
52 | ||
53 | g77 has a set of functions that somewhat parallels the gcc front end | |
54 | when it comes to building decls: | |
55 | ||
56 | Internal Function (one we define, not just declare as extern): | |
57 | int yes; | |
58 | yes = suspend_momentary (); | |
59 | if (is_nested) push_f_function_context (); | |
60 | start_function (get_identifier ("function_name"), function_type, | |
61 | is_nested, is_public); | |
62 | // for each arg, build PARM_DECL and call push_parm_decl (decl) with it; | |
63 | store_parm_decls (is_main_program); | |
c7e4ee3a | 64 | ffecom_start_compstmt (); |
5ff904cd | 65 | // for stmts and decls inside function, do appropriate things; |
c7e4ee3a | 66 | ffecom_end_compstmt (); |
5ff904cd JL |
67 | finish_function (is_nested); |
68 | if (is_nested) pop_f_function_context (); | |
69 | if (is_nested) resume_momentary (yes); | |
70 | ||
71 | Everything Else: | |
72 | int yes; | |
73 | tree d; | |
74 | tree init; | |
75 | yes = suspend_momentary (); | |
76 | // fill in external, public, static, &c for decl, and | |
77 | // set DECL_INITIAL to error_mark_node if going to initialize | |
78 | // set is_top_level TRUE only if not at top level and decl | |
79 | // must go in top level (i.e. not within current function decl context) | |
80 | d = start_decl (decl, is_top_level); | |
81 | init = ...; // if have initializer | |
82 | finish_decl (d, init, is_top_level); | |
83 | resume_momentary (yes); | |

5ff904cd | 7884 | |
c7e4ee3a CB |
7885 | Normally the front end uses the back-end function |
7886 | variable_size to wrap SAVE_EXPR's around expressions | |
7887 | affecting the size/shape of an array so that the | |
7888 | size/shape info doesn't change during execution | |
7889 | of the compiled code even though variables and | |
7890 | functions referenced in those expressions might. | |
5ff904cd | 7891 | |
c7e4ee3a CB |
7892 | variable_size also makes sure those saved expressions |
7893 | get evaluated immediately upon entry to the | |
7894 | compiled procedure -- the front end normally doesn't | |
7895 | have to worry about that. | |
3cf0cea4 | 7896 | |
c7e4ee3a CB |
7897 | However, there is a problem with this that affects |
7898 | g77's implementation of entry points, and that is | |
7899 | that it is _not_ true that each invocation of the | |
7900 | compiled procedure is permitted to evaluate | |
7901 | array size/shape info -- because it is possible | |
7902 | that, for some invocations, that info is invalid (in | |
7903 | which case it is "promised" -- i.e. a violation of | |
7904 | the Fortran standard -- that the compiled code | |
7905 | won't reference the array or its size/shape | |
7906 | during that particular invocation). | |
5ff904cd | 7907 | |
c7e4ee3a | 7908 | To phrase this in C terms, consider this gcc function: |
5ff904cd | 7909 | |
c7e4ee3a CB |
7910 | void foo (int *n, float (*a)[*n]) |
7911 | { | |
7912 | // a is "pointer to array ...", fyi. | |
7913 | } | |
5ff904cd | 7914 | |
c7e4ee3a CB |
7915 | Suppose that, for some invocations, it is permitted |
7916 | for a caller of foo to do this: | |
5ff904cd | 7917 | |
c7e4ee3a | 7918 | foo (NULL, NULL); |
5ff904cd | 7919 | |
c7e4ee3a CB |
7920 | Now the _written_ code for foo can take such a call |
7921 | into account by either testing explicitly for whether | |
7922 | (a == NULL) || (n == NULL) -- presumably it is | |
7923 | not permitted to reference *a in various fashions | |
7924 | if (n == NULL) I suppose -- or it can avoid it by | |
7925 | looking at other info (other arguments, static/global | |
7926 | data, etc.). | |
5ff904cd | 7927 | |
c7e4ee3a CB |
7928 | However, this won't work in gcc 2.5.8 because it'll |
7929 | automatically emit the code to save the "*n" | |
7930 | expression, which'll yield a NULL dereference for | |
7931 | the "foo (NULL, NULL)" call, something the code | |
7932 | for foo cannot prevent. | |
5ff904cd | 7933 | |
c7e4ee3a CB |
7934 | g77 definitely needs to avoid executing such |
7935 | code anytime the pointer to the adjustable array | |
7936 | is NULL, because even if its bounds expressions | |
7937 | don't have any references to possible "absent" | |
7938 | variables like "*n" -- say all variable references | |
7939 | are to COMMON variables, i.e. global (though in C, | |
7940 | local static could actually make sense) -- the | |
7941 | expressions could yield other run-time problems | |
7942 | for allowably "dead" values in those variables. | |
5ff904cd | 7943 | |
c7e4ee3a CB |
7944 | For example, let's consider a more complicated |
7945 | version of foo: | |
5ff904cd | 7946 | |
c7e4ee3a CB |
7947 | extern int i; |
7948 | extern int j; | |
5ff904cd | 7949 | |
c7e4ee3a CB |
7950 | void foo (float (*a)[i/j]) |
7951 | { | |
7952 | ... | |
7953 | } | |
5ff904cd | 7954 | |
c7e4ee3a CB |
7955 | The above is (essentially) quite valid for Fortran |
7956 | but, again, for a call like "foo (NULL);", it is | |
7957 | permitted for i and j to be undefined when the | |
7958 | call is made. If j happened to be zero, for | |
7959 | example, emitting the code to evaluate "i/j" | |
7960 | could result in a run-time error. | |
5ff904cd | 7961 | |
c7e4ee3a CB |
7962 | Offhand, though I don't have my F77 or F90 |
7963 | standards handy, it might even be valid for a | |
7964 | bounds expression to contain a function reference, | |
7965 | in which case I doubt it is permitted for an | |
7966 | implementation to invoke that function in the | |
7967 | Fortran case involved here (invocation of an | |
7968 | alternate ENTRY point that doesn't have the adjustable | |
7969 | array as one of its arguments). | |
5ff904cd | 7970 | |
c7e4ee3a CB |
7971 | So, the code that the compiler would normally emit |
7972 | to preevaluate the size/shape info for an | |
7973 | adjustable array _must not_ be executed at run time | |
7974 | in certain cases. Specifically, for Fortran, | |
7975 | the case is when the pointer to the adjustable | |
7976 | array == NULL. (For gnu-ish C, it might be nice | |
7977 | for the source code itself to specify an expression | |
7978 | that, if TRUE, inhibits execution of the code. Or | |
7979 | reverse the sense for elegance.) | |

7981 | (Note that g77 could use a different test than NULL, |
7982 | actually, since it happens to always pass an | |
7983 | integer to the called function that specifies which | |
7984 | entry point is being invoked. Hmm, this might | |
7985 | solve the next problem.) | |
7986 | ||
7987 | One way a user could, I suppose, write "foo" so | |
7988 | it works is to insert COND_EXPR's for the | |
7989 | size/shape info so the dangerous stuff isn't | |
7990 | actually done, as in: | |
7991 | ||
7992 | void foo (int *n, float (*a)[(a == NULL) ? 0 : *n]) | |
7993 | { | |
7994 | ... | |
7995 | } | |
5ff904cd | 7996 | |
c7e4ee3a CB |
7997 | The next problem is that the front end needs to |
7998 | be able to tell the back end about the array's | |
7999 | decl _before_ it tells it about the conditional | |
8000 | expression to inhibit evaluation of size/shape info, | |
8001 | as shown above. | |
5ff904cd | 8002 | |
c7e4ee3a CB |
8003 | To solve this, the front end needs to be able |
8004 | to give the back end the expression to inhibit | |
8005 | generation of the preevaluation code _after_ | |
8006 | it makes the decl for the adjustable array. | |
5ff904cd | 8007 | |
c7e4ee3a CB |
8008 | Until then, the above example using the COND_EXPR |
8009 | doesn't pass muster with gcc because the "(a == NULL)" | |
8010 | part has a reference to "a", which is still | |
8011 | undefined at that point. | |
5ff904cd | 8012 | |
c7e4ee3a CB |
8013 | g77 will therefore use a different mechanism in the |
8014 | meantime. */ | |

8652 | Because COMMON-based variables can be referenced in the dimension |
8653 | expressions of dummy (adjustable) arrays, and because dummies | |

c7e4ee3a CB |
8659 | The current strategy is basically to always tell the back end about |
8660 | the COMMON area as a top-level external reference to just a block | |
8661 | of storage of the master type of that area (e.g. integer, real, | |
8662 | character, whatever -- not a structure). As a distinct action, | |
8663 | if initial values are provided, tell the back end about the area | |
8664 | as a top-level non-external (initialized) area and remember not to | |
8665 | allow further initialization or expansion of the area. Meanwhile, | |
8666 | if no initialization happens at all, tell the back end about | |
8667 | the largest size we've seen declared so the space does get reserved. | |

8669 | of the important things.) | |

8671 | Meanwhile, for COMMON variables themselves, just keep creating |
8672 | references like *((float *) (&common_area + offset)) each time | |
8673 | we reference the variable. In other words, don't make a VAR_DECL | |
8674 | or any kind of component reference (like we used to do before 0.4), | |
8675 | though we might do that as well just for debugging purposes (and | |

10401 | If expression is NULL, returns an integer zero tree. If it is not | |
10402 | a CHARACTER expression, returns whatever ffecom_ptr_to_expr | |
10403 | returns and sets the length return value to NULL_TREE. Otherwise | |
10404 | generates code to evaluate the character expression, returns the proper | |
10405 | pointer to the result, AND sets the length return value to a tree that | |
10406 | specifies the length of the result. | |
10407 | ||
10408 | If the length argument is NULL, this is a slightly special | |
10409 | case of building a FORMAT expression, that is, an expression that | |
10410 | will be used at run time without regard to length. For the current | |
10411 | implementation, which uses the libf2c library, this means it is nice | |
10412 | to append a null byte to the end of the expression, where feasible, | |
10413 | to make sure any diagnostic about the FORMAT string terminates at | |
10414 | some useful point. | |
10415 | ||
10416 | For now, treat %REF(char-expr) as the same as char-expr with a NULL | |
10417 | length argument. This might even be seen as a feature, if a null | |
10418 | byte can always be appended. */ | |

13387 | Called when a new symbol is seen after the exec transition or when more |
13388 | info (perhaps) is gained for an UNCERTAIN symbol. The symbol state when | |
13389 | it arrives here is that all its latest info is updated already, so its | |
13390 | state may be UNCERTAIN or UNDERSTOOD, it might already have the hook | |
13391 | field filled in if its gone through here or exec_transition first, and | |
13392 | so on. | |
5ff904cd | 13393 | |
c7e4ee3a CB |
13394 | The backend probably wants to check ffesymbol_retractable() to see if |
13395 | backtracking is in effect. If so, the FFE's changes to the symbol may | |
13396 | be retracted (undone) or committed (ratified), at which time the | |
13397 | appropriate ffecom_sym_retract or _commit function will be called | |
13398 | for that function. | |
5ff904cd | 13399 | |
c7e4ee3a CB |
13400 | If the backend has its own backtracking mechanism, great, use it so that |
13401 | committal is a simple operation. Though it doesn't make much difference, | |
13402 | I suppose: the reason for tentative symbol evolution in the FFE is to | |
13403 | enable error detection in weird incorrect statements early and to disable | |
13404 | incorrect error detection on a correct statement. The backend is not | |
13405 | likely to introduce any information that'll get involved in these | |
13406 | considerations, so it is probably just fine that the implementation | |
13407 | model for this fn and for _exec_transition is to not do anything | |
13408 | (besides the required FFE stuff) if ffesymbol_retractable() returns TRUE | |
13409 | and instead wait until ffecom_sym_commit is called (which it never | |
13410 | will be as long as we're using ambiguity-detecting statement analysis in | |
13411 | the FFE, which we are initially to shake out the code, but don't depend | |
13412 | on this), otherwise go ahead and do whatever is needed. | |
5ff904cd | 13413 | |
c7e4ee3a CB |
13414 | In essence, then, when this fn and _exec_transition get called while |
13415 | backtracking is enabled, a general mechanism would be to flag which (or | |
13416 | both) of these were called (and in what order? neat question as to what | |
13417 | might happen that I'm too lame to think through right now) and then when | |
13418 | _commit is called reproduce the original calling sequence, if any, for | |
13419 | the two fns (at which point backtracking will, of course, be disabled). */ | |

15218 | /* If we are processing a typedef statement, generate a whole new |
15219 | ..._TYPE node (which will be just an variant of the existing | |
15220 | ..._TYPE node with identical properties) and then install the | |
15221 | TYPE_DECL node generated to represent the typedef name as the | |
15222 | TYPE_NAME of this brand new (duplicate) ..._TYPE node. | |
5ff904cd | 15223 | |
c7e4ee3a CB |
15224 | The whole point here is to end up with a situation where each and every |
15225 | ..._TYPE node the compiler creates will be uniquely associated with | |
15226 | AT MOST one node representing a typedef name. This way, even though | |
15227 | the compiler substitutes corresponding ..._TYPE nodes for TYPE_DECL | |
15228 | (i.e. "typedef name") nodes very early on, later parts of the | |
15229 | compiler can always do the reverse translation and get back the | |
15230 | corresponding typedef name. For example, given: | |
5ff904cd | 15231 | |
c7e4ee3a | 15232 | typedef struct S MY_TYPE; MY_TYPE object; |
5ff904cd | 15233 | |
c7e4ee3a CB |
15234 | Later parts of the compiler might only know that `object' was of type |
15235 | `struct S' if it were not for code just below. With this code | |
15236 | however, later parts of the compiler see something like: | |
5ff904cd | 15237 | |
c7e4ee3a | 15238 | struct S' == struct S typedef struct S' MY_TYPE; struct S' object; |
5ff904cd | 15239 | |
c7e4ee3a CB |
15240 | And they can then deduce (from the node for type struct S') that the |
15241 | original object declaration was: | |
5ff904cd | 15242 | |
c7e4ee3a | 15243 | MY_TYPE object; |
5ff904cd | 15244 | |
c7e4ee3a CB |
15245 | Being able to do this is important for proper support of protoize, and |
15246 | also for generating precise symbolic debugging information which | |
15247 | takes full account of the programmer's (typedef) vocabulary. | |
5ff904cd | 15248 | |
c7e4ee3a CB |
15249 | Obviously, we don't want to generate a duplicate ..._TYPE node if the |
15250 | TYPE_DECL node that we are now processing really represents a | |
15251 | standard built-in type. | |
5ff904cd | 15252 | |
c7e4ee3a CB |
15253 | Since all standard types are effectively declared at line zero in the |
15254 | source file, we can easily check to see if we are working on a | |
15255 | standard type by checking the current value of lineno. */ | |
