Hi.
I've been working on porting compiler-rt/clang's support for address
sanitization (asan) to FreeBSD. So far I have it building and it
appears to work properly, however the build system expects to be able
to build 32 bit binaries on amd64.
amd64 doesn't include i386's machine/foo headers. The included patch
is my proposed solution:
Add i386 headers to /usr/include/i386, and in machine/foo.h, check if
it's a 32 bit build and include the appropriate header from i386.
For example machine/ucontext.h will include i386/ucontext.h if
compiled with -m32.
Thoughts?
If anyone's curious about the compiler_rt port, I have it at
github.com/dannomac/compiler-rt on the branch named freebsd.
Sorry for fencepost comment which may have no/little relevance here
Changing the hierarchy to ISA/bits may make cross compiling easier in
the future
