It looks like we never want to set TCG_TARGET_SIGNED_ADDR32 on 32-bit
hosts; maybe a compile-time assert could be added somewhere for
statically guaranteeing this?
I've placed a build-time assert in tcg/tcg.c.
- if (TCG_TARGET_REG_BITS > TARGET_LONG_BITS) {
+ if (TCG_TARGET_REG_BITS > TARGET_LONG_BITS && !guest_base_signed_addr32) {
Is there precedent of extracting predicates like this into some header
for reuse? However I agree that the current expression conveys enough
meaning without being overly complicated.
Depends on the expected scope of the predicate, I guess.
If it's private to tcg-target.c.inc, I'd put it in tcg.c.
If it's private to tcg in general, I'd put it in tcg-internal.h.
Beyond that, I guess it depends.
For this, I don't know what I'd call it that isn't more verbose than the
expression itself.
