[Bug middle-end/41343] [4.5 Regression] sysdeps/ieee754/dbl-64/dosincos.c from glibc causes excessive memory use

------- Comment #14 from jakub at gcc dot gnu dot org  2009-09-22 12:13 -------
Correction - artificial variables aren't needed, DW_TAG_dwarf_procedure with
just DW_AT_location with the expression or loclist is enough.
That's BTW something that a dwarf compactor could do - look at dwarf
expressions in DW_AT_location attributes and .debug_loc, see if there are
subexpressions that occur frequently and big enough that replacing them with 3
byte DW_OP_call2 <ref2> would be worthwhile, for those add
DW_TAG_dwarf_procedure at some low DIE offset (< 64KB into .debug_info).  GCC
could do that too of course, perhaps as a special pass over the debug info
before sizing it.
