[Gc] [PATCH] Implement boehm-gc for AARCH64:ILP32

[Andrew Pinski]

Hi,
This is a simple patch which allows all of the boehm-gc testsuite
that is included with GCC to pass for AARCH64:ILP32.
Basically we need to set CPP_WORDSZ to 32 and the alignment to 4 so we
detect pointers correctly.

OK for GCC? Bootstrapped and tested for aarch64-linux-gnu with no
regressions and many libjava testcases now pass.

OK for boehm-gc upstream? I don't have write access to upstream
sources though, if approved there please apply it also.

Thanks,
Andrew Pinski

GCC ChangeLog:
* include/private/gcconfig.h (CPP_WORDSZ): Correct for AARCH64:ILP32.
(ALIGNMENT): Correct for AARCH64:ILP32.

Hi Andrew,

Done for upstream master - https://github.com/ivmai/bdwgc/commit/b399b13b9e4be18c6a38d315bdb957303f0226d4
