implemented Setup.hs to build boehm cpp libs and install them;
[hs-boehmgc.git] / gc-7.2 / sparc_sunos4_mach_dep.s
1 !       SPARCompiler 3.0 and later apparently no longer handles
2 !       asm outside functions.  So we need a separate .s file
3 !       This is only set up for SunOS 4.
4 !       Assumes this is called before the stack contents are
5 !       examined.
