Three ICEs in regression tests with gcc-3.4-20030813


I built and tested gcc-3.4-20030813 / glibc-2.3.2 on
ppc405, ppc750, and sh4 today.  Regression test summaries available at
http://www.kegel.com/crosstool/current/summaries/
I'm only just starting to look at the results.  Here are three ICE's:

First, a problem that shows up on both powerpc variants.  The summaries
http://www.kegel.com/crosstool/current/summaries/powerpc-405-linux-gnu-gcc-3.4-20030813-glibc-2.3.2.gcc.sum
http://www.kegel.com/crosstool/current/summaries/powerpc-750-linux-gnu-gcc-3.4-20030813-glibc-2.3.2.gcc.sum
show:
FAIL: gcc.dg/altivec-5.c (test for excess errors)
The log shows:
gcc-3.4-20030813/gcc/testsuite/gcc.dg/altivec-5.c:12: internal compiler error: in extract_insn, at recog.c:2064


Second, a problem shows up in two tests only on sh4: the summary http://www.kegel.com/crosstool/current/summaries/sh4-unknown-linux-gnu-gcc-3.4-20030813-glibc-2.3.2.gcc.sum shows: FAIL: gcc.dg/compat/vector-2 c_compat_x_tst.o compile FAIL: gcc.dg/compat/vector-2 c_compat_y_tst.o compile The log shows: gcc-3.4-20030813/gcc/testsuite/gcc.dg/compat/vector-2_x.c:7: internal compiler error: in smallest_mode_for_size, at stor-layout.c:259 gcc-3.4-20030813/gcc/testsuite/gcc.dg/compat/vector-2_y.c:7: internal compiler error: in smallest_mode_for_size, at stor-layout.c:259


Third, a problem that shows up only on sh4: the summary http://www.kegel.com/crosstool/current/summaries/sh4-unknown-linux-gnu-gcc-3.4-20030813-glibc-2.3.2.gcc.sum shows: FAIL: g++.dg/ext/stmtexpr1.C (test for excess errors) The log shows: gcc-3.4-20030813/gcc/testsuite/g++.dg/ext/stmtexpr1.C:48: internal compiler error: in cp_expr_size, at cp/cp-lang.c:330

Are these results useful, or do the gcc developers already know about them?

Thanks,
Dan
