Subject: [CUDA] Use all 64 bits of GUID in __nv_module_id
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=52d4fabea811bf965104a5f6e8f22a55f08b1f03;p=clang

[CUDA] Use all 64 bits of GUID in __nv_module_id

getGUID() returns an uint64_t and "%x" only prints 32 bits of it.
Use PRIx64 format string to print all 64 bits.
