[Bug middle-end/27733] New: Large compile time regression

[danglin at gcc dot gnu dot org]

Relative to gcc version 4.0.4 20060507 (prerelease) (Debian 4.0.3-3),
gcc version 4.1.1 20060511 (prerelease) (Debian 4.1.0-4) and also my own
build of 4.2 exhibit a large increase in compile on the attached file.
On my c3k, the time goes from ~ 5 seconds to 49 minutes.

The compile command used is:

/usr/bin/hppa64-linux-gnu-gcc-4.1 -nostdinc -v alloc.i -mno-space-regs
-mfast-indirect-calls -mdisable-fpregs -march=2.0 -mschedule=8000 -O2 -Wall
-Wundef -Wstrict-prototypes -Wno-trigraphs -Wdeclaration-after-statement
-Wno-pointer-sign -fno-strict-aliasing -fno-common -fomit-frame-pointer
-ffunction-sections -S
