[Qemu-devel] [RCF PATCH 0/2] Improving TCG debug output

[alex . bennee]

From: Alex Bennée <address@hidden>

Hi,

These two patches have been sitting in my personal tree for a while
and I thought it was worth soliciting feedback as to their wider usefulness.

The first is simply an attempt to make tcg abort failures a little
less terse.

The second I found useful when I was debugging a complex set of TCG
ops for a round, shift and narrow implementation. The alternative was
to set up GDB and step through the generated target code (or just
infer from the copious dumps). The macro magic might be a bit much though.

Alex Bennée (2):
  tcg: add tcg_abort_dbg() for additional debug info
  tcg: add debug helpers tcg_debug_dump_i(32|64)
