The epiphany has, sort of: you read a control register, AND and/or OR
some mask(s) to the value,
and write it back.
If we knew the previous mode, we might elide and AND o

Hello,
I'd still wish to ping for the following set of patches. Those changes
does not impact other targets than SH4 but, as suggested by Joern, I
have hooked the macros and moved the SH4A specific support to the target
parts (so a different target can eventually implement other models than

Christian,
Respin of a long standing forgotten patch
(http://gcc.gnu.org/ml/gcc-patches/2006-12/msg01562.html).
This patch extends the mode-switching pass to toggle on/off a control
register status bit instead of setting the value. e.g on the SH4a to
support the FPCHG instruction used to switch FPU precision
