I can reproduce the ICE on sparc64-linux with 4.5-20100902 and 4.6-20100904 -Os
-m32. With -m64 or -O1/O2/O3 it doesn't ICE. 4.4-20100817 doesn't ICE.

I can't get this to ICE with latest version of 4.4, 4.5 or 4.6 branches.
The default_secondary_reload ICE is on a gcc_assert() so you must configure
with --enable-checking; --enable-checking

The smallest .o file that differs between stage2 and stage3 is sreal.o. Diffing

I have found a cure.

It's not a stage2/stage3 debug difference as far as I can tell. I've
recompiled every differing .o file with the stage 1/2/3 xgccs -fcompare-debug
without complaints.

This ICEs for me with 4.4-20100907 and the 4.5.1 release (-m32 -mno-fpu), but
not with 4.5-20100902 or 4.6-20100904.

Oops, that was with a locally modified 4.5-20100902. A vanilla 4.5

With 4.4.2 as base on gcc57 (and your PR45444 patch) I don't see the

I downloaded and installed cctools-590.12, and that did indeed solve the
gcc-4.1.0 bootstrap problem.
However, today I discovered that the newer cctools break gcc-3.4.x.

Any patch for gcc-3.4.6?
Yes, use the patch shown earlier in this thread,
or the equivalent one provided by crosstool.

Here's a standalone test case. This fails (returns 1 from main())
on armv5b-linux when compiled with gcc-3.4.4, 3.3.6, or 3.3.3,
at -O2 or -O1 -foptimize-sibling-calls. Disabling sibcall optimisation
hides the bug
