36422 2010-03-20 21:07:30 -0700 [Qt] Qt 4.6.2 does not build with ICC (QtWebKit, Ubuntu) 2014-02-03 03:16:20 -0800 1 1 1 Unclassified WebKit Platform 420+ PC Linux RESOLVED INVALID Qt, QtTriaged P3 Normal --- 1 qtcreatorgeek webkit-unassigned benjamin cmarcelo hausmann kent.hansen menard ogoffart oldest_to_newest 202266 0 qtcreatorgeek 2010-03-20 21:07:30 -0700 Compilation of WebKit fails when Qt is compiled with ICC on Ubuntu. Errors are generated when trying to compile "asm volatile" statements. Please see the attached file that has make output for one of the same multiple errors. Environment: Ubuntu 9.10, Qt 4.6.2, ICC 11.1.069 202362 1 hausmann 2010-03-21 16:13:26 -0700 Could you attach the missing file that shows the compilation error messages? 202904 2 51389 qtcreatorgeek 2010-03-22 20:13:28 -0700 Created attachment 51389 Fragment of make output that shows a compilation error. 215291 3 kent.hansen 2010-04-21 06:57:05 -0700 Yeah, I can reproduce this. ICC defines __GNUC__, which causes COMPILER(GCC) to be defined. But, as with the MSVC compatibility (see http://trac.webkit.org/changeset/51484), it seems it's not fully compatible. According to http://software.intel.com/sites/products/documentation/studio/composer/en-us/2009/compiler_c/intref_cls/common/intref_data_align_ma_ia_linux_ia.htm , GNU-style inline assembly should be supported. I tried with __asm and __asm__ as well, no luck. If Google translated the comment to http://qtcreatorgeek.blogspot.com/2010/03/qt-icc-ubuntu_20.html correctly, it's only a problem with ia32, but I can't confirm that. I was able to make JavaScriptCore compile by doing the following in JavaScriptCore/wtf/Platform.h: @@ -73,7 +73,7 @@ /* COMPILER(GCC) - GNU Compiler Collection */ /* --gnu option of the RVCT compiler also defines __GNUC__ */ -#if defined(__GNUC__) && !COMPILER(RVCT) +#if defined(__GNUC__) && !COMPILER(RVCT) && !defined(__INTEL_COMPILER) #define WTF_COMPILER_GCC 1 #define GCC_VERSION (__GNUC__ * 10000 + __GNUC_MINOR__ * 100 + __GNUC_PATCHLEVEL__) #endif i.e. don't define COMPILER(GCC) if we're compiling with Intel Compiler. I don't know how far-reaching that change will be, however. (There are about 40 places besides JITStubs.cpp that check for COMPILER(GCC).) QtScript 4.7 tests all pass. Doing the __INTEL_COMPILER check locally in JITStubs.cpp is not enough; then you hit #error "JIT not supported on this platform." So unless somebody knows how to do the inline assembly with ICC, the alternative is to disable the JIT on linux-icc. Note that other projects have also had problems with ICC defining __GNUC__: http://groups.google.com/group/perl.perl6.internals/browse_thread/thread/1d658e87ded6601e http://www.mail-archive.com/perl5-changes@perl.org/msg13780.html 312814 4 ogoffart 2010-11-23 06:52:28 -0800 The fix on x86 is there: http://gitorious.org/+qtwebkit-developers/webkit/qtwebkit/commit/1f6f32d8010ee71dc33daafc7746ec0f302f26ae Note that the exact same fix need to be done as well for x86_64 342311 5 benjamin 2011-01-30 09:05:55 -0800 Olivier, should we close this bug? Does trunk build on ICC? 356483 6 menard 2011-02-23 15:23:11 -0800 Qt 4.7 branch doesn't even build on a 64 bits Arch with icc 64 :). I tried the same patch as the 32 bits in the 64 part but no luck. Perhaps I mess up it is late already :). Olivier ? 357003 7 menard 2011-02-24 08:12:30 -0800 Update : Trunk does not build even with JIT disabled :). 357330 8 menard 2011-02-24 13:26:32 -0800 My version is 11.1 perhaps I should upgrade to 12. 358004 9 menard 2011-02-25 10:18:29 -0800 Trunk builds now fine with ICC 12.x (one SVG patch is still pending review). It compiles and seems to run fine with JIT off so I suggest that in order to be safe we should deactivate JIT. If we build with JIT it crashes. We don't have that much resources to track ICC so let's play it safe and let's disable JIT by default. If some Indiana Jones wants to try with JIT then they just pass DEFINES+=ENABLE_JIT=1. Anyway the long term is perhaps V8 perhaps it's worth to check there too. Any objections? If not then I will make the patch. 358008 10 menard 2011-02-25 10:21:57 -0800 Disable JIT for ICC if it was not clear enough :) 975118 11 jturcotte 2014-02-03 03:16:20 -0800 === Bulk closing of Qt bugs === If you believe that this bug report is still relevant for a non-Qt port of webkit.org, please re-open it and remove [Qt] from the summary.
