>Description:
When compiling attached t.i (a further simplified version
of the amd74xx.i subitted for PR 5428) with 'gcc -c -march=i686 -O2', you get an ICE, this time at flow.c:526:
t.i: In function `ata66_amd74xx':
t.i:13: Internal compiler error in verify_wide_reg_1, at flow.c:526
Output of 'gcc -v' is:
