Subject: tcg: extend max tcg opcodes when using 64-on-32bit
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7a86d29a7e16e738d749cfece8857d8902790875;p=qemu.git

tcg: extend max tcg opcodes when using 64-on-32bit

When running a 64 bit guest on a 32 bit host, we tend to use more TCG ops
than on a 64 bit host. Reflect that in the reserved opcode amount constant.
