Subject: Enable mprotect-based incremental GC for Linux/arm and Linux/aarch64
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=88338a5cf4a9521ac546ecdd9fc9f9b7a7b2caf0;p=gc

Enable mprotect-based incremental GC for Linux/arm and Linux/aarch64

* include/private/gcconfig.h [AARCH64 && LINUX && !(GC_LINUX_THREADS
&& REDIRECT_MALLOC)] (MPROTECT_VDB): Define macro (similar to X86_64
and I386 cases).
* include/private/gcconfig.h [ARM32 && LINUX && !(GC_LINUX_THREADS
&& REDIRECT_MALLOC)] (MPROTECT_VDB): Likewise.
