[Qemu-devel] [PATCH 00/18] tcg: decouple tcg_target_long from pointer size

[Richard Henderson]

There are several targets for which we have 64-bit registers, even
when compiling for a 32-bit address space.  Of course, compiling
qemu for a 64-bit address space is better, considering the large
amount of virtual memory that we generally want to allocate.  That
said, it's not always an option.

This patch set adjusts everywhere that used tcg_target_long when it
really meant intptr_t, and then enables the easiest such target to
actually test: x32 (x86_64 with 32-bit pointers).

Tested in a vm installed with gentoo's x32 environment.
