Quoting Joern Rennecke :
You use a clobber with a matching constraint for alternative 1 and X for
other alternatives. Make sure the patten is not named.
P.S.: Actually, named is fine if you use a match_scratch, or if it's not
a standard name.

Quoting "Paulo J. Matos" :
I have a situation in writing a specific condition on an md file.
I have an insn with 2 alternatives and then I use which_alternative to
generate the assembler code but if which_alternative == 1 I am
clobbering a register. How can I tell gcc that if it matches 1, a

Hi all,
I have a situation in writing a specific condition on an md file.
I have an insn with 2 alternatives and then I use which_alternative to
generate the assembler code but if which_alternative == 1 I am
clobbering a register. How can I tell gcc that if it matches 1, a
given register is clobbe
