[Bug c/37106] [4.4 Regression] ICE: in mems_in_disjoint_alias_sets_p, at alias.c:278
--- Comment #10 from ghazi at gcc dot gnu dot org 2008-10-14 08:10 --- (In reply to comment #9) Well, I guess then the first thing to ask for is for both the gcc.target/i386/opt-1.c and gcc.target/i386/opt-2.c tests to be extended so that they are run with -fPIC. It would be helpful to know if current gcc trunk on i386 linux fail these test with -fPIC to determine if this issue is darwin specific. I confirm the opt-1/opt-2 failures on i686-linix and x86_64-linux when using -fpic or -fPIC: http://gcc.gnu.org/ml/gcc-testresults/2008-10/msg00958.html http://gcc.gnu.org/ml/gcc-testresults/2008-10/msg00907.html The issue is not darwin-specific. -- ghazi at gcc dot gnu dot org changed: What|Removed |Added CC||ghazi at gcc dot gnu dot org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2008-10-14 08:10:59 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37106

The issue is not darwin-specific. Digging the archives the failures on x86_64-linux when using -fpic or -fPIC appeared between: http://gcc.gnu.org/ml/gcc-testresults/2008-07/msg02246.html and http://gcc.gnu.org/ml/gcc-testresults/2008-07/msg02337.html Kaveh do you have a way to know the corresponding revisions? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37106

--- Comment #3 from howarth at nitro dot med dot uc dot edu 2008-10-13 13:46 --- Can you try regressing r141079 and see if that suppresses the problem on -m32 for i686-apple-darwin9? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37106

Both revisions are the same: 141077 is for trunk (what I build and probably you also), 141079 is for the ira-merge branch I am not using. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37106

--- Comment #4 from dominiq at lps dot ens dot fr 2008-10-13 13:59 --- Can you try regressing r141079 ... This revision is for the ira-merge branch, the revision for trunk is r141077 and given the revision window and the fact that it cannot be r141078 since the failures did not appear with this patch, and that the other revisions are either gfortran or date stamps, I think it is the only candidate without further testing. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37106

--- Comment #7 from howarth at nitro dot med dot uc dot edu 2008-10-13 16:11 --- Can you try the failing test cases with -fno-PIC to see if these issues are related to the fact that darwin defaults to -fPIC? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37106

--- Comment #2 from dominiq at lps dot ens dot fr 2008-10-13 08:55 --- I now get the same error for gcc.target/i386/opt-1.c and opt-2.c also in 32 bit mode (default). This appeared between revision r141074 (with the patch for pr37808) and r141083. Note the ICE for gcc.target/i386/hot-1.c disappeared between r139622 and r139843. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37106
