Hi!

Did some benchmarking of gcc-2.95.1 configured both with and 
without --haifa-enable on 4 diffent CPUs:

	- i486 DX266   - no evident difference between 2 compilers (with
                                   and without --enable-haifa)
	- Pentium 200MMX -  the same
	- K6-2 300 - HAIFA enabled compiler generates about 20% faster
	                     code for -O0 and -O2. For -O3 difference is smaller or
                             is absent in some conditions
        - Pentium 2 350MHz - no evident difference
	
So it remains unclear whether I should use --enable-haifa for binaries 
I'll upload to ftp.delorie.com
