Uh, you have to un-comment the line 315 of the comunpack.f test. The testcase,
as attached, produces good code. Un-commenting line 315, you will get:
.L80:
movl $0x40000000, (%esp)
call powf
fstps -152(%ebp)
negl -136(%ebp)
fildl -136(%ebp)
fstps 4(%esp)
movl $0x41200000, (%esp)
call powf
Note that only one argument is loaded to the stack before first powf.
Without -fforce-address on un-commented testcase, we got:
.L80:
fildl -132(%ebp)
fstps 4(%esp)
movl $0x40000000, (%esp)
call powf
fstps -140(%ebp)
negl -128(%ebp)
fildl -128(%ebp)
fstps 4(%esp)
movl $0x41200000, (%esp)
call powf
