Description Felipe Alfaro Solana 2003-12-05 09:48:26 UTC 
Description of problem:
-----------------------
When trying to compile the linux kernel sources for 2.6.0-test11,
gcc-ssa stops with a fatal error while trying to compile function
request_irq() in file arch/i386/kernel/irq.c:

arch/i386/kernel/irq.c: In function `request_irq':
arch/i386/kernel/irq.c:545: internal compiler error: in
get_expr_operands, at tree-dfa.c:402
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions.

Version-Release number of selected component (if applicable):
gcc-ssa-3.5ssa-0.20031202.105

How reproducible:
Always

Steps to Reproduce:
1. Download linux-2.6.0-test11.tar.bz2 from
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.0-test11.tar.bz2
2. Apply the attached "gcc-ssa.patch" patchfile to modify the Makefile
in order to use "gcc-ssa" instead of the "gcc" compiler.
3. Copy the attached "config" file to the root of the source tree and
name it ".config".
4. make oldconfig
5. make V=1 bzImage

The gcc-ssa compiler will fail as noted above.
  
Actual results:
---------------
gcc-ssa is unable to compile the linux kernel.

Expected results:
-----------------
Well, I wasn't really expecting gcc-ssa (in its current alpha release)
to be able to compile the kernel, but, ey! I had to try ;-)

Additional info:
----------------
binutils-2.14.90.0.6-4
glibc-2.3.3-1
Running on linux 2.6.0-test11

I haven't included the pre-processed source code as the linux kernel
is generally wide available and the steps to reproduce the error are
fairly simple.

Patch to use gcc-ssa to build the kernel

You should apply this patch to a pristine 2.6.0-test11 linux kernel source tree
in order to use "gcc-ssa" instead of the normal "gcc".

Linux config file use to trigger the error

You should copy this config file into the root of the kernel source tree with
the ".config" name. Next, a "make oldconfig" should be run to import it.
Comment 3 Felipe Alfaro Solana 2004-01-25 14:21:57 UTC 
OK, it seems gcc-ssa- is able to successfully compile 2.6.2-rc1-mm3 
kernel. However, the resulting kernel is not bootable as it freezes 
hard while "Uncompressing Linux kernel...".
