[Qemu-devel] [PATCH v2 00/20] target-sparc: Cleanup handling of temps

[Richard Henderson]

The primary goal of this patch set is to have all references to windowed
registers to go through new routines that have access to DisasContext.
This is a prerequisite to any change in how windowed registers might be
managed.

Since such a goal must of course touch get_src[12], and therefore touch
the use of the cpu_src[12] temporaries, a secondary goal of the patch set
became to clean up all of the temporary management within the translator.
And in particular eliminate the 6 "global" temps that we currently allocate
inside gen_intermediate_code_internal.

Changes v1->v2:
  * Fix use without initialization that clang found that gcc did not.
    (Was I compiling without optimization last time?)
  * Re-based vs master.
