On the other hand, it does expose many issues in middle-end as well as in backend.

This one character change, from POINTERS_EXTEND_UNSIGNED < 0 to POINTERS_EXTEND_UNSIGNED != 0 creates a working x32 GCC. You should upgrade to the latest CWSDPMI if you experience such problems, and if that doesn't help, bump up the size of CWSDPMI heap using CWSPARAM. For x86-64, it is -16*1023*1024.

  • You're saying it's a regression, but the known-to-work field is empty.
  • One cause of problems with accessing memory is incorrect setting of the wait states in your BIOS setup, or too aggressive CPU cache mode that your motherboard cannot support reliably, or

  • OK with these changes.
  • We recently changed our old build machine and this has introduced some oddities into the system.

Comment 4 Richard Biener 2011-02-01 11:50:39 UTC Sounds similar to other reports that build on i?86 without -msse and a target attribute that enables some more SSE features.

I was able to isolate the code causing the error in my case (using the sizeof operator on the third argument of the memcpy function) and submitted a support ticket (1-163827). But if during any of the following optimization passes set_cfun is called to some other function which has different target options, target_reinit is called, which calls free_after_compilation which will clear x_rtl.

clang sometimes does better than gcc, but also trips up sometimes. –Peter Cordes Mar 5 at 4:45 | show 1 more comment Did you find this question interesting? Lu PR middle-end/55142 * config/i386/i386.c (legitimize_pic_address): Properly handle REG + CONST. (ix86_print_operand_address): Set code to 'k' when forcing addr32 prefix. It's clear that Richard's change, aka the un-sign-extension of sizetype constants, is an earthquake here. Check the FAQ section of this forum.

Tested on x32.

Q: GCC aborts with "Internal compiler error" when compiling a large C++ program. The problem is that tree_rest_of_compilation calls init_emit and lots of other init* functions and assumes x_rtl will stay initialized until expansion. But nowhere in those intrinsics calls do I see the name of a hardware register, so it must be filled in during code generation. –rici Mar 5 at 4:28 my review here Best regards, Bernd post edited by nice - 2009/12/07 15:32:25 #5 aschen0866 Super Member Total Posts : 4017 Reward points : 0 Joined: 2006/01/08 22:18:32Location: San Diego Status: offline RE: C30
