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.
