Description: mksnapshot uses too much memory on 32-bit mipsel
Author: Jérémy Lal <kapouer@melix.org>
Last-Update: 2020-06-03
Forwarded: https://bugs.chromium.org/p/v8/issues/detail?id=10586
This ensures that we reserve 500M instead of 2G range for codegen
ensures that qemu-mips can allocate such large ranges
