Subject: [PGO] Fix remaining bugs in ProfData template file (when used by compiler-rt)
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=94e1578270cf5533642af4a977b5790fee8dec58;hp=a7e61b03221280ffe5d3ce843f1e8be5192ec8d0

[PGO] Fix remaining bugs in ProfData template file (when used by compiler-rt)

1. move const qualifier out of raw header field type as runtime use of the header
   needs to initialze the fields
2. use C style casting for integer types.
