[Bug c/109507] New: Optimizer creates incorrect program
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109507 Bug ID: 109507 Summary: Optimizer creates incorrect program Product: gcc Version: 12.1.0 Status: UNCONFIRMED Keywords: wrong-code Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: aran at 100acres dot us Target Milestone: --- Created attachment 54854 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54854=edit Example program. The attached program should print 0 and does with optimization level zero (0). However, with optimization at any non-zero value (e.g., g, s, 1, 2) it prints 1. This is on an Intel I7-2600. The code that the optimizer writes reduces to a single test instruction that checks if x is less or equal to zero. However, this is incorrect for the most negative number. To reproduce compile the attached file with -O0 and with -O1.

[Bug target/39570] cabs and cabsf are named differently on NetBSD 5
--- Comment #7 from aran at 100acres dot us 2009-03-28 18:13 --- (In reply to comment #5) Another fix is to #undef TARGET_C99_FUNCTIONS as obviously netbsd is another OS without a clue ... Please explain how an OS with a clue would handle this problem. Older binaries that use the pre-c99 complex structure links to the existing linker symbols, cabs and cabsf. Changing the meaning of these symbols to the c99 meaning would break these legacy programs. It seems cluefull to decorate these symbols with __c99_ and provide a rename in the header.

[Bug fortran/39570] New: cabs and cabsf are named differently on NetBSD 5
On NetBSD 5.0, cabs and cabsf, defined in complex.h, are renames of __c99_cabs and __c99_cabsf. The build-in definitions in f95-lang.c specifically name cabs and cabsf. On NetBSD 5.0, these are provided for compatibility and emit a linker warning when linking.

--- Comment #4 from aran at 100acres dot us 2009-03-28 01:34 --- Subject: Re: cabs and cabsf are named differently on NetBSD 5 What is beyond me is how darwin_patch_builtings gets called. It looks like it is called from rs6000.c in rs6000_init_builtins via the macro SUBTARGET_INIT_BUILTINS. i386.c doesn't appear to have this infrastructure. I am not familiar enough with gcc internals to know what the impacts might be on other platforms if I start making changes here. Also, these renames are only for NetBSD 5. How do I detect the os version. The darwin example uses darwin_macosx_version_min. Is there a NetBSD analog?

What gcc does for darwin (and this is a hack, mind you), is basically replace the standard C99 builtins with darwin-specific ones. You have to do the same for NetBSD. See the following files in gcc/config/: * darwin.c * darwin-ppc-ldouble-patch.def The code in darwin_patch_builtin() changes the assembler name of the builtin function to a custom, darwin-specific version. E.g. cabsl has a PATCH_BUILTIN defines, so its DECL_NAME is the normal cabls name but its assembler name becomes _cabsl_$LDBL128. You need to do something similar (but probably less ugly) for NetBSD to make this work. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39570
