[Bug c++/13753] New: miscompilation with -fnew-ra on xCHM

[gcc-bugzilla at gcc dot gnu dot org]

	Internal compiler error with the following report:
	g++ -DHAVE_CONFIG_H -I. -I. -I.. -I../art  -I/usr/lib/wx/include/gtk2-2.4 -DGTK_NO_CHECK_CASTS -D__WXGTK__ -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES  -O2 -fmove-all-movables -fnew-ra -finline-limit=600 -maccumulate-outgoing-args -minline-all-stringops -fprefetch-loop-arrays -mno-align-stringops -frename-registers -mfpmath=387 -march=athlon-xp -fomit-frame-pointer -pipe  -W -Wall -MT chmfile.o -MD -MP -MF ".deps/chmfile.Tpo"
	bitfiddle.inl: In function `u_int64_t sr_int(unsigned char*, int*, unsigned
	char, unsigned char, size_t&)':
	bitfiddle.inl:148: internal compiler error: in reloads_to_loads, at
	ra-rewrite.c:1068
	Please submit a full bug report,
	with preprocessed source if appropriate.
	(please don't care about the kernel version/patch, it's just my personal modification to make this radeon9800XT work with the framebuffer)

How-To-Repeat:
	With this CFLAGS and the version of gcc, emerge xchm in gentoo.
	CFLAGS="-O2 -fmove-all-movables -fnew-ra -finline-limit=600 -maccumulate-outgoing-args -minline-all-stringops -fprefetch-loop-arrays -mno-align-stringops -frename-registers -mfpmath=387 -march=athlon-xp -fomit-frame-pointer -pipe"

Fix:
	remove -fnew-ra and it compiles perfectly.
