memory details for 131610
This is the detailed memory usage for the compiler
euler-5% /pkgs/gcc-mainline/bin/gcc -v
Using built-in specs.
Target: x86_64-unknown-linux-gnu
Configured with: ../../mainline/configure --prefix=/pkgs/gcc-mainline
--enable-languages=c --enable-checking=release --with-gmp=/pkgs/gmp-4.2.2
--with-mpfr=/pkgs/gmp-4.2.2 --enable-gather-detailed-mem-stats
Thread model: posix
gcc version 4.3.0 20080117 (experimental) [trunk revision 131610] (GCC)
The maximum memory I observed in top was 10.2 GB.
Kenny, I can't tell whether your patch from
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34400#c50
has been committed; will that improve the situation, too?
