[Rui Ueyama via Phabricator via llvm-commits]

ruiu added a comment.

I applied this patch and built clang with ThinLTO. Here is the generated file:

$ less bin/clang-10.json 
{"traceEvents":[{"pid":1,"tid":185412,"ph":"X","ts":181,"dur":1441864,"name":"Parse input files","args":{"detail":""}},{"pid":1,"tid":185412,"ph":"X","ts":12564626,"dur":541606,"name":"OptModule","args":{"detail":"ld-temp.o"}},{"pid":1,"tid":185412,"ph":"X","ts":1454232,"dur":17946238,"name":"LTO","args":{"detail":""}},{"pid":1,"tid":185412,"ph":"X","ts":19461534,"dur":15275,"name":"GC","args":{"detail":""}},{"pid":1,"tid":185412,"ph":"X","ts":19721702,"dur":1241569,"name":"Write output file","args":{"detail":""}},{"pid":1,"tid":185412,"ph":"X","ts":2,"dur":20963276,"name":"ExecuteLinker","args":{"detail":""}},{"pid":1,"tid":185413,"ph":"X","ts":0,"dur":20963276,"name":"Total ExecuteLinker","args":{"count":1,"avg ms":20963}},{"pid":1,"tid":185414,"ph":"X","ts":0,"dur":17946237,"name":"Total LTO","args":{"count":1,"avg ms":17946}},{"pid":1,"tid":185415,"ph":"X","ts":0,"dur":1441864,"name":"Total Parse input files","args":{"count":1,"avg ms":1441}},{"pid":1,"tid":185416,"ph":"X","ts":0,"dur":1241569,"name":"Total Write output file","args":{"count":1,"avg ms":1241}},{"pid":1,"tid":185417,"ph":"X","ts":0,"dur":541704,"name":"Total OptModule","args":{"count":2,"avg ms":270}},{"pid":1,"tid":185418,"ph":"X","ts":0,"dur":15274,"name":"Total GC","args":{"count":1,"avg ms":15}},{"cat":"","pid":1,"tid":0,"ts":0,"ph":"M","name":"process_name","args":{"name":"ld.lld"}}]}

This file seems much smaller than yours. What am I missing? (I couldn't download your file because the server times out perhaps due to the file size.)
