[Qemu-devel] [PATCH 0/4] tcg: Add debug facilities for TCGv

[Andreas Färber]

Hello,

Working on 16- and 20-bit targets using TARGET_LONG_BITS == 32, I found it too
easy to accidentally use, e.g., tcg_temp_free() in place of tcg_temp_free_i32().
In case of 78k0/rl78 it may not practically matter yet, but it complicates
going from a 32-bit target to 64 bits, as in the case of arm.

This series refactors TCG code to allow using a dedicated struct for TCGv,
to make variable type mismatches show up as compilation errors.

This series only adds the infrastructure but does not enable it by default.
A series adapting target-i386 will be posted independently as an RFC.

Regards,
Andreas
