Thank you, Mikael, and apologies for not testing sooner. The fix in attachment 24326 works perfectly. I tested it on gcc 4.5.2, and the "if" that is changed is at line 509 on that version, but the structure is exactly the same. Now: # echo | gcc -dM -E - -march=native gcc -v -Q --help=target -march=native 2>&1 | grep march /usr/libexec/gcc/i586-pc-linux-gnu/4.5.2/cc1 -E -v help-dummy -D_FORTIFY_SOURCE=2 -march=k6-3 --param l1-cache-size=32 --param l1-cache-line-size=32 --param l2-cache-size=128 -mtune=k6 -fhelp=target -dM -march= k6-3 # cc -march=native -E -v - </dev/null 2>&1 | grep cc1 /usr/libexec/gcc/i586-pc-linux-gnu/4.5.2/cc1 -E -quiet -v - -D_FORTIFY_SOURCE=2 -march=k6-3 --param l1-cache-size=32 --param l1-cache-line-size=32 --param l2-cache-size=128 -mtune=k6 # Additionally I have recompiled my whole system with -march=native, and it is working perfectly. I would be very grateful if this were able to be incorporated into gcc.
