Hello,
I would like to test V8 on xcode/mac, using ARM simulator (of V8). But
I couldn't find any information about how to do that.
The xcodeproj file works fine as a standalone javascript shell using
x86 ISA. However, as an engineer for embedded systems, I also want to
test it using ARM simulator of V8. (I want to trace the arm binaries
generated from JS codes.) I could do it using 'scons', but then I
couldn't use the debugging facility of xcode. (Using gdb only is not
very efficient for analyzing V8..)
I couldn't find any doc/article on this subject. (All I found was just
a source patch that enabled this feature.) Is there anyone who can
help me use xcode to build/test/debug V8 using ARM simulator?
(Actually, I tried setting "debug | v8_shell-arm" as a build target in
xcode. But, it also failed producing the following log. I used v8 of
r5780, which should be a very recent version.)
