version: CVS mainline
host: i386-linux
target: sh-elf
I have one testsample which was compiling properly on a 128 meg system
with:
-O2 -m4 -fnew-ra
I believe starting today, it started to be killed by the OS for excessive
memory usage:
[tm@localhost gcc]$ ./cc1 -O2 -m4 -fnew-ra -da engine_c.i

Has anything changed in the new regalloc on mainline to consume more
memory?
