Hi,This is basically OK, though we are currently in regression bugfixes only mode (where a regression is defined as something that previously worked, but no longer works). It's not clear to me how this is fixing any regressions since it appears to be mostly an optimization patch. If there is a hunk that is directly responsible for fixing bugs, we can break that out into its own patch that could be installed now, but I simply don't see which it would be.
The following patch generates bit instructions for logical operations on the H8 target. It also generates instructions in #xx:3 and #xx:4 immediate addressing modes for H8SX target.
The patch fixes 272 regressions on the H8SX target and overall it fixes 525 regressions. The original patch was earlier posted in the following Bugzilla link, http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38091
A few issues that came up have been addressed in this version of the patch.
The patch "h8300_bit_insn.patch" is attached.
Regards,
