Subject: cmd/compile: set PPC64's MAXWIDTH as other architectures
X-Git-Tag: go1.18beta1~109
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=8da66a35cab2de4f7ce0215c47929be624eeb03d;p=gostls13.git

cmd/compile: set PPC64's MAXWIDTH as other architectures

PPC64's MAXWIDTH is set as 1<<60 whereas on other 64-bit
architetures it is set as 1<<50. Set to 1<<50 for consistency. The
toolchain cannot handle such large program anyway.

May fix PPC64 build.
