Patch to add BeOS/x86 support
Jason Merrill

Tue Jan 11 14:48:00 GMT 2000
The BeOS is an odd puppy, gratuitously incompatible with Unix
conventions in a number of ways. Several of these ways are new to
gcc, so they have been parameterized.
The BeOS uses a farm of include directories rather than one primary
one, as with NeXTstep. CROSS_SYSTEM_HEADER_DIR allows the port to
override SYSTEM_HEADER_DIR to one of these directories for cross
builds.
LIBRARY_PATH is for dld, and BELIBRARIES is for ld.
Older versions of BeOS had a 256K stack, which wasn't anywhere near
enough to run gcc using the normal alloca, so it was necessary to
force use of the C alloca. Newer versions have a 1M stack, which is
still pretty iffy, though less of a problem since gcc's alloca usage
has decreased.
The folks at Be wanted 'gcc foo.c' to produce 'foo' rather than
'a.out'; this patch implements that change for the BeOS port. How do
people feel about this inconsistency?

* configure.in (i?86-*-beos{pe,elf,}*): Recognize.
* i386/t-beos, i386/x-beos, i386/xm-beos.h: New files.
* i386/beos-elf.h, i386/beos-pe.h: New files.
* Makefile.in (CROSS_SYSTEM_HEADER_DIR): New.
* cross-make (SYSTEM_HEADER_DIR): Define using
CROSS_SYSTEM_HEADER_DIR.
* gcc.c (LIBRARY_PATH_ENV): Provide default.
(process_command): Use it.
(main): Likewise. Kill trailing = from env vars.
(build_search_list): Put it back.
* collect2.c (main): Use LIBRARY_PATH_ENV.
* configure.in (GCC_NEED_DECLARATIONS): Add environ.
* toplev.c: Use NEED_DECLARATION_ENVIRON.
* tm.texi (Frame Layout): Document SMALL_STACK.
* c-common.c (c_common_nodes_and_builtins): Check it.
* system.h: Undef alloca after including glibc's <stdlib.h>,
if USE_C_ALLOCA is defined.
* gcc.c (set_input): New fn.
(main): After all input files are compiled, reset the input file
info to the first.
* aclocal.m4 (rindex, index): If already defined, don't attempt
to redefine.
* ginclude/varargs.h: (__va_list__): Define ifndef.
* ginclude/stdarg.h: Likewise.
* ginclude/stddef.h (__WCHAR_TYPE__) [BEOS]: Use int
instead of unsigned char.
* hash.h (true, false, boolean): Undef before enum.

+ 2 for %edx (gnu regno = 1)
+ 3 for %ebx (gnu regno = 3)
+ 4 for %esp (gnu regno = 7)
+ 5 for %ebp (gnu regno = 6)
+ 6 for %esi (gnu regno = 4)
+ 7 for %edi (gnu regno = 5)
+ The following three DWARF register numbers are never generated by
+ the SVR4 C compiler or by the GNU compilers, but SDB on x86/svr4
+ believes these numbers have these meanings.
+ 8 for %eip (no gnu equivalent)
+ 9 for %eflags (no gnu equivalent)
+ 10 for %trapno (no gnu equivalent)
+ It is not at all clear how we should number the FP stack registers
+ for the x86 architecture. If the version of SDB on x86/svr4 were
+ a bit less brain dead with respect to floating-point then we would
+ have a precedent to follow with respect to DWARF register numbers
+ for x86 FP registers, but the SDB on x86/svr4 is so completely
+ broken with respect to FP registers that it is hardly worth thinking
+ of it as something to strive for compatibility with.
+ The version of x86/svr4 SDB I have at the moment does (partially)
+ seem to believe that DWARF register number 11 is associated with
+ the x86 register %st(0), but that's about all. Higher DWARF
+ register numbers don't seem to be associated with anything in
+ particular, and even for DWARF regno 11, SDB only seems to under-
+ stand that it should say that a variable lives in %st(0) (when
+ asked via an `=' command) if we said it was in DWARF regno 11,
+ but SDB still prints garbage when asked for the value of the
+ variable in question (via a `/' command).
+ (Also note that the labels SDB prints for various FP stack regs
+ when doing an `x' command are all wrong.)
+ Note that these problems generally don't affect the native SVR4
+ C compiler because it doesn't allow the use of -O with -g and
+ because when it is *not* optimizing, it allocates a memory
+ location for each floating-point variable, and the memory
+ location is what gets described in the DWARF AT_location
+ attribute for the variable in question.
+ Regardless of the severe mental illness of the x86/svr4 SDB, we
+ do something sensible here and we use the following DWARF
+ register numbers. Note that these are all stack-top-relative
+ numbers.
