Subject: [bindings/go] Fix building on 32-bit systems (ARM etc.)
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7405c60df8d53e90dee2f174f6d96bf73f3e7b7c;p=llvm

[bindings/go] Fix building on 32-bit systems (ARM etc.)

Summary:
The patch in https://reviews.llvm.org/D53883 (by me) fails to build on 32-bit systems like ARM. Fix the array size to be less ridiculously large. 2<<20 should still be enough for all practical purposes.
