http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47150 Jakub Jelinek jakub at gcc dot gnu.org changed: What|Removed |Added CC||jakub at gcc dot gnu.org --- Comment #4 from Jakub Jelinek jakub at gcc dot gnu.org 2011-01-03 11:16:35 UTC --- The problem is in save_expr called by convert_to_complex when converting non-COMPLEX_EXPR _Complex float expression to _Complex double. As this is not c_save_expr that is called there (and can't, because convert_to_complex is used in non-Cish FEs), c_fully_fold is not called on the argument and as further c_fully_fold doesn't dive into SAVE_EXPRs, nothing afterwards fully folds it either, which means it survives until gimplification and crashes there. An ugly fix would be duplicate the problematic part of convert_to_complex in c-convert.c (if converting COMPLEX_TYPE to a different COMPLEX_TYPE and expression is not COMPLEX_EXPR) and use c_save_expr there instead.

By replacing this to test -f, it should working for native and cross-compile. There were also comments that the path is sometimes wrong. Using test -f should fix the immediate regression - but it would be better not to hardcode paths at all. Presumably the issue is that some particular stylesheets are needed *in the path searched by the tools being tested for*, which may depend on how those tools were configured and may not be in /usr at all. So it would be better to have a feature test - run the tools (if found) on a suitable document to see if they can find the required stylesheets. Perhaps the libstdc++ maintainers could comment on what the actual feature required is for which a path test is being used as a bad proxy?

As this is not c_save_expr that is called there (and can't, because convert_to_complex is used in non-Cish FEs), c_fully_fold is not called on the argument and as further The non-C-family front ends seems generally to be using it in their implementations of convert, the legacy magic-name langhook. If this could be eliminated (making remaining users in the language-independent compiler use fold_convert unless they really need language-specific semantics) then quite possibly the convert functions in those front ends could go away and much of convert.c could move into c-family code (it does checks for invalid conversions and gives errors for them, which is clearly something that belongs in front ends) - while some of those front ends use their own convert functions internally, they may well not need special semantics for complex types that fold_convert doesn't have. But this certainly isn't a Stage 4 fix c_fully_fold doesn't dive into SAVE_EXPRs, nothing afterwards fully folds it either, which means it survives until gimplification and crashes there. An ugly fix would be duplicate the problematic part of convert_to_complex in c-convert.c (if converting COMPLEX_TYPE to a different COMPLEX_TYPE and expression is not COMPLEX_EXPR) and use c_save_expr there instead. In view of the above and the notion that convert_to_complex really belongs in the front ends, this seems reasonable.

[Bug c/47146] Floating point to integer conversions
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47146
--- Comment #3 from Pierre Innocent babelart at yahoo dot com 2011-01-03
17:12:05 UTC ---
Dear kargl:
Sorry, I was not specific enough. It is the integer conversion that seem
to be wrong,for example the following two lines:
fprintf( stdout, Float 100.0 * 0.3894949=%d\n, 100.0 * elapsed );
fprintf( stdout, Float 100 * 0.3894949=%d\n, 100 * elapsed );
both produce the value '-536870912'.
I also downloaded the C99 integer to float conversion test code; and they
generated two many failures. I also believe the compiler should round resulting
integer values when stripping decimals off.
Regards,
Pierre Innocent

If you change all your floating point constants to include
a f
suffix (e.g., 100.0f, 0.3894949f, etc), then you get
laptop:kargl[149] cc -o z a.c -ffloat-store ./z
Float 0.3894949=0.389495
Float 0.3894949 * 100.0=38.949490
Integer Cast 0.3894949 * 100.0=38
Float=38.949490
Integer=38
--
Float 0.39=0.39
Float 0.39 * 100.0=39.00
Integer Cast 0.39 * 100.0=39
Float=39.00
Integer=39
which looks like the desired output. As Jonathan
mentions, you
have several intermediate results that are double not
float.
Add the fact that 0.39 is not exactly representable, which
your output of Float 0.39 * 100.0=38.99 clearly
shows,
you've miss interpreted your results.

May I know why do you ask? To see if the change indeed causes important regressions in real-world code. The change was done to be less surprising when doing TBAA based disambiguations as people regularly expect void * to be similar to char * and also do not really handle multiple-indirect pointers the correct way. Thus, we now miscompile less not strictly conforming programs. IIRC, it was distilled from some large program. There was a difference when compiling it with and without LTO, and I reported it as a bug 43201. Ah, that explains it (LTO did the pointer TBAA thing for a long time).

[Bug testsuite/46912] [4.6 Regression] Test failures for g++.dg/plugin/*plugin*.C on powerpc-apple-darwin9
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46912 --- Comment #7 from Richard Guenther rguenth at gcc dot gnu.org 2011-01-03 20:59:41 UTC --- (In reply to comment #5) On Dec 16, 2010, at 2:06 PM, iains at gcc dot gnu.org wrote: gcc/system.h : # define bool unsigned char This is wrong. The solution is simple: #define bool _Bool on darwin. Arguably, this is correct for every non-broken system as well. We can't rely on GCC or C99 support. The correct fix is to define bool to unsigned int for darwin then (and pay the space efficience loss price). Richard.
