Ok, so this extends the infrastructure to support insns which set an
arbitrary number of registers, but currently specifically handles only
REG_INC situations (which set two registers). I'm not against
{0,1,infinity}, but wonder if this case really deserves the
complexity: post/pre-inc/decrementing
Hello,
This is a re-submission of the patch to support instructions with REG_INC_NOTE.
(http://gcc.gnu.org/ml/gcc-patches/2011-04/msg01309.html)
It contains a minor change from the previous submission suggested by
Richard Sandiford: to use reg_referenced_p instead of
rtx_referenced_p.
The patch
Hello,
The attached patch extends the current implementation to analyze
instructions with REG_INC_NOTE.
Tested on ppc64-redhat-linux (bootstrap and regtest) SPU (only regtest)
and arm-linux-gnueabi (bootstrap c and regtest) configured with
--with-arch=armv7-a --with-mode=thumb.
OK for mainline?
