Subject: gcc in perl is broken compared to mingw.org gcc
Download (untitled) / with headers
text/plain 7.4k
The GCC 4.4.3 in Strawberry Perl 5.12.3 32 bit and the GCC 4.4.7 in Strawberry Perl 5.14.2 are broken. The latest Mingw.org release which has GCC 4.6.2 isn't broken. The strawberry perl GCCs are incapable of using GCC builtins under -O0 optimization level preventing the creation of any PEs which do not link to the CRT. GCC builtins are functionally identical to #pragma intrinsic on MSVC. A sample program is included. It is called memcpy.c. It was compiled with "gcc memcpy.c -nostdlib -lkernel32 -o memcpy.exe -v -Wall -O0" using the 2 different Strawberry Perl GCCs mentioned above. Each time the S. Perl GCCs converted the __builtin_memcpy function to memcpy, which is a CRT function, then fail when they can't link to the CRT. Mingw.org GCC does NOT exhibit this. I brought the problem up on the mingw mailing list here previous http://sourceforge.net/mailarchive/message.php?msg_id=28930444 They determined it was a problem with Strawberry Perl GCC, not Mingw.org GCC. Reading through the Changelogs from 4.4 to 4.6 of GCC here http://gcc.gnu.org/gcc-4.4/changes.html does not reveal anything about this problem. Show quoted text

Thanks for your report. The upcoming strawberry perl 5.16.0 will be probably bundled with gcc-4.6.3 I'll check whether the new compiler still suffers from this issue. However keep in mind that we are not using gcc+c-runtime from http://mingw.org project but from http://mingw-w64.sf.net project (it is mostly due to the much better 64bit support). So for us it would be better if you can bring this issue to mingw-w64-public@lists.sourceforge.net mailing list (see https://lists.sourceforge.net/lists/listinfo/mingw-w64-public) -- kmx

unfortunately gcc-4.6.3+mingw-w64 runtime (which is a candidate to be bundled with upcoming strawberry perl) seems to throw an error: c:\test> gcc memcpy.c -nostdlib -lkernel32 -o memcpy.exe -v -Wall -O0 ... memcpy.c:(.text+0xea): undefined reference to `memcpy' Which is - if I understand correctly - the buggy behaviour, right?

Correct. Mingw64 refused to fix it claiming its a problem with GCC. Then why does it compile fine with Mingw.org GCC? https://sourceforge.net/tracker/?func=detail&atid=983354&aid=3502290&group_id=202880 I included the 2 build logs from mingw.org gcc and mingw64 gcc as attachments.

Hi, a hint from Mark Dootson (his gcc-4.6.3 binaries are about to be used in strawberry perl 5.16.0) - try the following workaround with mingw-w64: c:\test> i686-w64-mingw32-gcc.exe memcpy.c -nostdlib -lkernel32 -o memcpy.exe -v -Wall -O0 -mtune=pentiumpro It really seems to be a gcc issue in in the target specific specification files which are different for mingw.org and mingw-w64.sf.net -- kmx

On S Perl 5.14 x64, mtune=native failed, tried to link to CRT On S Perl 5.12 x86, mtune=pentiumpro failed, tried to link to CRT On Mingw64 latest x86 (mingw-w32-bin_i686-mingw_20111219.zip), mtune=pentiumpro success but it tried to link to crt if mtune is removed Basically, -O0 is useful for step through debugging. MS Intrinsics always work. Mingw.org builtins always work. Mingw64 builtins never under -O0. I'll guess the mtune in newer Mingw64s somehow becomes a -O under the hood, but is there a magic -fturn-me-on option for mingw64 that fixes everything? Whats a "target specific specification files"? Do mingw.org and mingw64 "patch" or "change" the compile time settings or the C code of their GCCs? I compared the -dumpspecs of latest .org and latest w64, I see nothing relevant to builtins. But im not a gcc person. Thanks for the work around, but it doesn't work on existing Strawberry Perls, only yet to be born ones.

Hi, This is a gcc feature / issue. mingw.org always passes -mtune=i386 as a default. So, with 4.6.3 compiler from perlmingw.sf.net if you also pass - mtune=i386 then that 'works' fine too. Likewise, if you pass -mtune=pentium4 to mingw.org ( so overriding the default ) then that will fail. (as will -mtune=generic and a number of other processor options) mingw.org passing '-i386' is the odd behaviour. According to gcc docs, the default behaviour should be -mtune=generic Anyhow, it is a gcc issue and you may not get any joy getting this fixed as it may be a feature rather than a 'bug'. Using builtins is regarded as an optimization so by default is switched off by gcc if you pass -O0. gcc should allow you to override the behaviour by calling __builtin_memcpy - but this bit of gcc seems to fail. But it is a gcc issue, not a mingw issue. Mingw code doesn't mess miss the __builtins_ prefix. I suspect that in the gcc code, specifying certain -mtune params counts as an optimization - hence the unintentional side effect of passing - mtune=i386 meaning gcc compiles builtins for you. There is no workaround for 64 bit mingw. I realise this isn't helpful but is is the answer. On a wider note, why would you want to avoid linking to msvcrt in a debugging app? regards Mark

The Windows API is so feature loaded, its quite easy to write windows perl XS mods, or optimize perl XS mods, to NOT use the CRT. Not using the CRT saves 1KB in the PE image because of the various static linked configuration code and data of the CRT (signals/callbacks, C level TLS, C++ object support, C++ exception/SEH marriage). Kernel32 has some string processing functions. User32 has a sprintf and charupper. Shlwapi has more string processing, but pre 5.12 perls dont link to it and it has no byte processing. But unless you will runtime link with ntdll, there is no non-CRT memcpy anywhere in the windows api AFAIK. CopyMemory is a macro for memcpy, not a Kernel32 func. MoveMemory is only available on Win NT. MSVC intrinsics fit the job perfectly. GCC builtins would too, except for everything above :-( I think you explain correctly why .org and w64 are different, .org selects a "i386" processor target optimization level. I guess there is no way around finding a CRT or pseudo CRT (ntdll) at runtime to avoid the overload of using the CRT directly on GCC, unless you test compile something using builtins with the current $Config{ccflags} and $Config{optimize} key and/or the user's makefile.pl overrides in the WriteMakefile hash.

Well, it is still a bug in GCC I think. In the GCC source in gcc/builtins.c is the following code /* When not optimizing, generate calls to library functions for a certain set of builtins. */ if (!optimize && !called_as_built_in (fndecl) && DECL_ASSEMBLER_NAME_SET_P (fndecl) && fcode != BUILT_IN_ALLOCA && fcode != BUILT_IN_FREE) return expand_call (exp, target, ignore); The 'called_as_built_in()' function should return true if you called the function as __builtin_memcpy, but I think it probably does not work on Windows at all. You should note that __builtin_memcpy is ALWAYS translated to 'memcpy' - it just depends on whether gcc includes the implementation for linking or not. For any -O level other than -O0, 'optimize' is true. I think some settings for mtune must set one of the other options to return true (or maybe change 'optimize', but I didn't have the time to track gcc option setting through the source. As I understand your reply, the benefit you seek is a 1k saving in PE image size? If I were you I'd live with it and add -O0 -lmsvcrt to your flags. Alternatively take up the potential bug above with the gcc folks. Regards Mark

The builtins are so buggy and unpredictable (pentium4 vs generic vs i386 vs x64 mtune flags) I declare they are unusable in a XS library. The only safe way I see to do this is to parse the makemaker makefile macros then do test compiles with those flags on that particular gcc build to see if the builtins work without a C Lib at a particular combination of flags, which seems too complicated and too easy to break. Instead I made a solution of finding an existing C loaded in the process and then runtime linking to it. Much less than 1 KB in the PE file. You can close this bug now.
