Subject: GCC and FirstBit()

Author: Frank Phillips

Can anyone point me to a freeware version of Eugene’s FirstBit(), LastBit() and
PopCnt() assembly functions for Linux (gcc), preferably in the form of a
#define for inclusion in a header file.

Much as I like Linux, my program is about 20 to 30 percent slower under Linux
than it is when compiled with MS VC++ under Windows.

Profiling shows that the array based lookup to find the first or last bit is
taking most time.
