--- Comment #4 from ebotcazou at gcc dot gnu dot org 2010-09-22 06:06 --- Jakub, what do you think? gcc.c reads: %Sremove all occurrences of -S from the command line. Note - this command is position dependent. % commands in the spec string before this one will see -S, % commands in the spec string after this one will not. and the spec is gcc/java/jvspec.c:jvgenmain_spec. I think that the above means that 'as' shoudn't see -findirect-dispatch but your change breaks that. -- ebotcazou at gcc dot gnu dot org changed: What|Removed |Added CC||jakub at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44095

[Bug java/44095] [4.5/4.6 Regression] massive java failures due to -findirect-dispatch breakage on sparc64-linux
--- Comment #3 from ebotcazou at gcc dot gnu dot org 2010-09-21 21:45 --- Java is severely broken on sparc64-linux with gcc 4.5/4.6, which is a major regression from 4.4: http://gcc.gnu.org/ml/gcc-testresults/2010-05/msg00853.html (4.6 broken) http://gcc.gnu.org/ml/gcc-testresults/2010-05/msg00681.html (4.5 broken) http://gcc.gnu.org/ml/gcc-testresults/2010-05/msg00472.html (4.4 works) The detailed test suite logs show that _every_ -findirect-dispatch test case SEGFAULTs shortly after startup. I've bisected trunk and identified r155622 as the cause: Author: jakub Date: Mon Jan 4 16:02:41 2010 New Revision: 155622 URL: http://gcc.gnu.org/viewcvs?root=gccview=revrev=155622 Log: PR driver/42442 * gcc.c (SWITCH_IGNORE_PERMANENTLY): Define. (do_self_spec): For switches with SWITCH_IGNORE set set also SWITCH_IGNORE_PERMANENTLY. (check_live_switch): Check SWITCH_IGNORE_PERMANENTLY instead of SWITCH_IGNORE. [...] The main difference is that in the working compiler, the java classes are assembled with -K PIC but the generated main() is not, while in the broken compiler both the java classes and the generated main() are assembled with -K PIC. Thanks for the detailed analysis. I note that gcc/java/jvspec.c has %findirect-dispatch, and that PR42442 is about correcting the handling of %match=native. Clearly something here doesn't mix well. My interpretation is that the %findirect-dispatch for cc1 used to cancel the effect of -findirect-dispatch for subsequent programs invoked by the driver, in particular 'as' in this case. Jakub's change disables this cancellation so -findirect-dispatch is passed to 'as' and thus the kludge I put in ASM_SPEC for Linux triggers, which breaks because cc1 hasn't compiled the file in PIC mode. -- ebotcazou at gcc dot gnu dot org changed: What|Removed |Added Last reconfirmed|2010-09-20 21:40:00 |2010-09-21 21:45:21 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44095

--- Comment #1 from ebotcazou at gcc dot gnu dot org 2010-09-20 21:59 --- Even though the use of the m constraint will fix this testcase, m cannot be used in general, because it allows the operand to be offsetable. Right. The casx instruction will not tolerate an offset. According to gcc info page, V should be just like m, but not offsetable. Wonder why V does not work when m does in this case. Because essentially all memory operands are offsettable on the SPARC. And the operand required by 'casx', i.e [reg], is also offsettable. The fix is to use 'casx [%0]' instead and adjust. -- ebotcazou at gcc dot gnu dot org changed: What|Removed |Added CC||ebotcazou at gcc dot gnu dot ||org Status|UNCONFIRMED |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36558

(PLUGINCFLAGS): Define as $(COMPILER_FLAGS). is wrong and broke again plugins testing with the C compiler on non-C99 native platforms like Solaris 8 and 9. The purpose of PLUGINCC is to have it redefined for each compilation stage so that it will eventually be set to the compiler used to compile the tested compiled; for the stage3 compiler, it should be the stage2 compiler. This is necessary because plugins testing uses the auto-host.h file of the compiler used to compile the tested compiler, not the auto-host.h file of the base compiler. Setting it to a fixed value like $(COMPILER_FLAGS) breaks the scheme because it's stuck to the base compiler. -- ebotcazou at gcc dot gnu dot org changed: What|Removed |Added CC||ebotcazou at gcc dot gnu dot ||org Known to fail|4.5.0 |4.5.0 4.6.0 Known to work|4.6.0 | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42843

[Bug tree-optimization/45421] [4.6 regression] Ada bootstrap failure on IRIX 6.5: SIGBUS in sem_aggr.sort_case_table
--- Comment #4 from ebotcazou at gcc dot gnu dot org 2010-09-02 21:59

It's IVOPTS so no way to get a reduced testcase. The analysis is for the stock
sem_aggr.adb file compiled at -O2 -gnatpg for IA-64. We have:
table.68_174 = .builtin_alloca (D.5147_173);
with pi-align = 16
D.5252_266 = *table.68_174;
with pi-align = 16 and then
MEM[(struct sem_aggr__case_bounds[(size_type) PLACEHOLDER_EXPR struct
sem_aggr__case_table_type___XUP.P_BOUNDS-LB0:PLACEHOLDER_EXPR struct
sem_aggr__case_table_type___XUP.P_BOUNDS-UB0 = PLACEHOLDER_EXPR struct
sem_aggr__case_table_type___XUP.P_BOUNDS-LB0 ? (size_type) PLACEHOLDER_EXPR
struct sem_aggr__case_table_type___XUP.P_BOUNDS-UB0 : (size_type)
PLACEHOLDER_EXPR struct sem_aggr__case_table_type___XUP.P_BOUNDS-LB0 + -1]
*)D.5252_266][D.6519_896]{lb: 1 sz: 12};
is replaced with
MEM[(struct sem_aggr__case_bounds[(size_type) PLACEHOLDER_EXPR struct
sem_aggr__case_table_type___XUP.P_BOUNDS-LB0:PLACEHOLDER_EXPR struct
sem_aggr__case_table_type___XUP.P_BOUNDS-UB0 = PLACEHOLDER_EXPR struct

struct sem_aggr__case_table_type___XUP.P_BOUNDS-UB0 : (size_type)
PLACEHOLDER_EXPR struct sem_aggr__case_table_type___XUP.P_BOUNDS-LB0 + -1]
*)D.6658_890]
in IVOPTS. And copy_ref_info reads:
/* We can transfer points-to information from an old pointer
or decl base to the new one. */
But now duplicate_ssa_name_ptr_info duplicates more than the points-to info,
it also duplicates the alignment info, which is wrong for arrays since the
base decl (pointed to by D.5252_266) can be more aligned than the individual
elements (pointed to by D.6658_890).
Tentative patch (I cannot test it on IA-64 before next week):

--- Comment #9 from ebotcazou at gcc dot gnu dot org 2010-08-27 14:36 --- I successfully built gcc on Solaris 10 using these versions of gmp/mpfr/mpc: gmp 4.3.2 mpfr 2.4.2 mpc 0.8.1 The instructions on the prerequisites.html page you reference below say to use those versions (or later). I'd recommend listing what versions you have tested gcc with and say simply that other versions haven't been tested. Thanks for your feedback. I'm going to add a blurb to the platform-specific instructions. I originally used the latest version of those three libraries: gmp 5.0.1 mpfr 3.0.0 mpc 0.8.2 Those three libraries _will_ work when building gcc on Linux or AIX--but not Solaris (you get the internal compiler error message in the bug report I originally submitted). I tried various combinations as well on Solaris (e.g. gmp 4.3.2, mpfr 2.4.2, and mpc 0.8.2), but only using the three earlier versions (gmp 4.3.2, mpfr 2.4.2, mpc 0.8.1) worked. Do you confirm that going from MPC 0.8.1 to 0.8.2 alone is problematic with GCC 4.1.2 as the base compiler? -- ebotcazou at gcc dot gnu dot org changed: What|Removed |Added GCC build triplet||sparc-sun-solaris2.* GCC host triplet||sparc-sun-solaris2.* GCC target triplet||sparc-sun-solaris2.* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45407

--- Comment #7 from ebotcazou at gcc dot gnu dot org 2010-08-25 20:07 --- I did notice that the SUNWspro compilers were used to compile the latest versions of mpfr mpc we use. Should I try re-compiling mpfr and mpc with gcc and then rebuilding gcc 4.5.1? The problematic ones are GMP and MPFR. You should run 'make check' in the build dir once you have compiled them. I am using the latest versions of mpfr (3.0.0) and mpc (0.8.2). I didn't see anything in: http://gcc.gnu.org/install/prerequisites.html about certain gcc versions miscompiling either of those packages. Yes, but we cannot test all combinations of libraries so sticking with the recommended versions is the safest approach. These are regularly tested in conjunction with the compiler. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45407
