[PATCH] Re: Rewrite i386 string operation expansion


Hello!

Your patch:

2006-11-19 Jan Hubicka <jh@suse.cz>

        * gcc.target/i386/memcpy-1.c: Adjust size.
        * testsuite/gcc.dg/visibility-11.c: Likewise.

        ...
        (decide_alg): New function.
        ...

crashes for -minline-all-stringops for certain targets:

gcc -O2 -march=pentium4 -minline-all-stringops gcc.dg/i386/memcpy-1.c

memcpy-1.c: In function âtâ:
memcpy-1.c:16: internal compiler error: in decide_alg, at
config/i386/i386.c:13510
Please submit a full bug report, ...etc...

Also crashes for -march=pentium, -march=k6 and -march=nocona.

Attached patch fixes this failure. Bootstrapped on i686-pc-linux-gnu.


2006-11-29 Uros Bizjak <ubizjak@gmail.com>

	config/i386/i386.c (decide_alg): For TARGET_INLINE_ALL_STRINGOPS
	initialize alg to algs->size[0].alg.

OK for mainline?

Uros.
