compiler slowdown in 4.3 development

[Bruno Haible]

Hi,

Here's a case of a function whose compilation with -O2 -g (the default with
autoconf) on Linux/x86 has slowed down by 67% since the 4.2.2 release.

$ time gcc -c -O2 -g -Wall sha512.c

Measured user time.

gcc 3.2.2           42.2 sec
gcc 3.3.6           71 sec
gcc 3.4.4           29.0 sec
gcc 4.0.4           24.5 sec
gcc 4.1.2           12.6 sec
gcc 4.2.2           10.7 sec
gcc 4.3-20080215    17.9 sec

Bruno
