Subject: Clobbering two registers
Date: Wed, 12 May 2010 16:17:00 -0000 [thread overview]
Message-ID: <AANLkTinEaz7duLhA38ozWqOLlH_CuwWbKUmb_tT2D0JE@mail.gmail.com> (raw)
Hi all,
How can I say in the machine architecture that to generate code for a
particular insn I need any two registers for intermediate operations?
To get one I think that (clobber (match_operand ...)) will work but
what if I want two? Can I add two clobbers on the same define_insn
rule?
Cheers,
