Extended Description

(this is my first bug report here, so please be gentle ;) )

While compiling llvm-gcc-4.2 on Linux/x86 (Fedora Core 4, 32-bit), I ran into an ICE during stage1.

More specifically, the following command fails:

/work/LLVM/llvm-gcc-4.2-obj/./gcc/xgcc -B/work/LLVM/llvm-gcc-4.2-obj/./gcc/ -B/work/LLVM/llvm-gcc-4.2-bin/i686-pc-linux-gnu/bin/ -B/work/LLVM/llvm-gcc-4.2-bin/i686-pc-linux-gnu/lib/ -isystem /work/LLVM/llvm-gcc-4.2-bin/i686-pc-linux-gnu/include -isystem /work/LLVM/llvm-gcc-4.2-bin/i686-pc-linux-gnu/sys-include -O2 -O2 -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -I. -I. -I../../llvm-gcc-4.2/gcc -I../../llvm-gcc-4.2/gcc/. -I../../llvm-gcc-4.2/gcc/../include -I../../llvm-gcc-4.2/gcc/../libcpp/include -I../../llvm-gcc-4.2/gcc/../libdecnumber -I../libdecnumber -I/home/kehoste/work/LLVM/llvm/include -I/work/LLVM/llvm-obj/include -g0 -finhibit-size-directive -fno-inline-functions -fno-exceptions -fno-zero-initialized-in-bss -fno-toplevel-reorder -fno-omit-frame-pointer

-o crtbegin.o

with

../../llvm-gcc-4.2/gcc/crtstuff.c:1: internal compiler error: Aborted

Running valgrind on it produces the output below. It seems the call to 'erase' at llvm::PMDataManager::removeNotPreservedAnalysis(llvm::Pass*) (PassManager.cpp:628) is the cause of this?

Devang is out on vacation for the rest of the week. Devang, can you take a look at this when you get back? It looks passmgr related.

Kenneth,

Would it be possible for you to extract some debugging information out of Pass Manager ? Add -fdebug-pass-structure on the llvm-gcc-4.2 command line that crashes and paste output here. Thank you.

[lattner]

ping! Is this reproducible? If not it should be closed.

ping! Is this reproducible? If not it should be closed.

I'm sorry I haven't provided the requested information yet, but I just have been too busy. I still want to work on getting the Fortran front-end fully working, and will hopefully be able to do that in the upcoming weeks. Chasing down this bug will be my first task.

I don't know if this is reproducible (nobody has mentioned seeing the same problem so far). Anyone?

[llvmbot]

A number of invalid memory usage bugs were fixed recently, so maybe this is fixed. I never saw it personally.

A number of invalid memory usage bugs were fixed recently, so maybe this is
fixed. I never saw it personally.

I've tried the current SVN head version of llvm-gcc-4.2 and LLVM, and the problem seems to solved. I'm still running into problems (see below), but from what I can tell they are not related to llvm-gcc but rather to a problem with gcc and older glibc versions.

As far as I'm concerned, this is a closed book...

It seems originally reported bug is now fixed. Please open new PR for other issues.
