Subject: [PATCH] add qemu-wrapper support
|
|
V8's JIT infrastructure requires binaries such as mksnapshot and mkpeephole to
|
be run in the host during the build. However, these binaries must have the
|
same bit-width as the target (e.g. a x86_64 host targeting ARMv6 needs to
|
produce a 32-bit binary). To work around this issue, cross-compile the
|
binaries for the target and run them on the host with QEMU, much like
|
gobject-introspection.
|
|
However, for the host-variant we do not want to use a
|
qemu-wrapper, so add @MAYBE_WRAPPER@ to the needed files and sed the path to
|
the qemu-wrapper on target builds, and remove @MAYBE_WRAPPER@ entirely on
|
host-builds.
