New issue 706 by [email protected]: GYP/Xcode/Chromium build support for
x86_64 v8
http://code.google.com/p/v8/issues/detail?id=706
For my next trick, I’m going to make x86_64 v8 buildable on the Mac via
GYP/Xcode in a
“comfortable” way. ”Comfortable” means that the architecture selection can
be done by the user
via Xcode settings (or GYP settings in this case), and multiple
architectures may be built
simultaneously for “fat” (universal) output.
On the Mac, the build environment will stop setting any V8_TARGET_ARCH_*
macros. In the
absence of any V8_TARGET_ARCH_* macro being set externally, v8 will choose
a target
architecture appropriate for the host, in the same way that it currently
detects V8_HOST_ARCH_*.
All of the _ia32.cc and _x64.cc will be compiled on the Mac. Each of these
will have an #ifdef
guard to ensure that the files are only built when compiling for the
relevant architecture.
In order to support universal builds, the snapshot-and-compile procedure
will need to change to
support multiple architectures. I’ll accomplish this in a driver script.
This is currently a lower
priority, and may lag behind the other work.
There may also be bugs in v8 on x86_64 on the Mac. I’ll correct these as
they come up.
