Subject: [PATCH 0/3] output *memory* operands need their address as *input*
Date: Sun, 21 Feb 2021 23:28:31 +0100 [thread overview]
Message-ID: <20210221222834.7974-1-luc.vanoostenryck@gmail.com> (raw)
These patches fix a problem with the linearization of asm statements
with output memory operands. These operands need to have their address
generated before the asm instruction but was generated after it.
Note: the problem wasn't visible when the address was a symbol
because the OP_SYMADDR producing the address is simplified
away at some later stage with the symbol directly handled
by the memory operation.
Luc Van Oostenryck (3):
asm: add testcase for problem with output addresses
asm: factor out add_asm_rule() from add_asm_{in,out}put()
asm: output *memory* operands need their address as *input*
