When compiling a C++ file, gcc 4.0.0 and 4.0.1 20050507 prerelease report an
internal compiler error:
> /gcc-test/bin/g++ ice.cpp -O2
ice.cpp: In constructor 'SomeException::SomeException(const char*, ...)':
ice.cpp:21: internal compiler error: in calc_dfs_tree, at dominance.c:376
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
> /gcc-test/bin/g++ -v
Using built-in specs.
Target: powerpc-linux
Configured with: ../gcc-4.0-20050507/configure --enable-languages=c,c++ --
prefix=/gcc-test --with-gnu-as --with-gnu-ld --with-system-zlib --without-
included-gettext --enable-threads=posix --enable-haifa --enable-sjlj-exceptions
powerpc-linux
Thread model: posix
gcc version 4.0.1 20050507 (prerelease)
When not using -O2 or when using -O2 -msoft-float, the ICE isn't reported. This
points to
/* Save FP registers if needed. */
if (DEFAULT_ABI == ABI_V4
&& TARGET_HARD_FLOAT && TARGET_FPRS
&& ! no_rtl
&& next_cum.fregno <= FP_ARG_V4_MAX_REG)
branch in gcc/config/rs6000/rs6000.c whose contents causes the problem (directly
or indirectly).
I have managed to create a minimal testcase for the problem and will attach it
to this report.

The isolated snippet causing the problem
I'm including the .cpp file and not the .i file since it doesn't need to be
preprocessed.

Huh, the problem is that sjlj exception code is tacked on to the end of basic
block 0, instead of the end of the prologue.
