[Qemu-devel] [PATCH 0/2] tcg: If DEBUG_TCGV, distinguish TCGv_ptr from TCGv_i32/TCGv_i64

[Peter Maydell <peter.maydell@linaro.org>]

This patch series enhances the type checking of TCG values done when
compiling with debugging enabled, so that it can detect confusion of
TCGv_ptr values with whichever of TCGv_i32 and TCGv_i64 corresponds to
the pointer-width type on the compile host. This means that such
errors will always be compile failures, rather than only failing on
one of the two kinds of compile host.

In particular, this would have caught the recent compile error
I introduced...

I've tested this on both 32 and 64 bit hosts, with a full compile
for all targets. Note that to get a clean debug compile for both
hosts (whether with or without this patchset) you'll need to have
applied the following recent patches which all fix compile problems:

 * http://patchwork.ozlabs.org/patch/97559/
   (target-arm: Fix compilation failure for 64 bit hosts)
 * http://patchwork.ozlabs.org/patch/97418/
   (target-s390x: Fix wrong argument in call of tcg_gen_shl_i64())
 * http://patchwork.ozlabs.org/patch/96665/
   (ppc: Fix compilation for ppc64-softmmu)
