Subject: [PATCH] gcc-go: Use int64 type as offset argument for mmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Without this patch, Go run-time memory allocation fails on 32-bit architectures:
fatal error: runtime: cannot allocate memory
runtime stack:
runtime.dopanic__m
:0
runtime.throw
:0
:0
:0
runtime.systemstack
:0
runtime.addrRanges.init
:0
runtime.pageAlloc.init
:0
runtime.mheap.init
:0
runtime.schedinit
