[compiler-rt] dd1ea9d - Reland: [Coverage] Revise format to reduce binary size

[Vedant Kumar via llvm-commits]

Sorry about the breakage, I’ve disabled the test in f82ae3ad while I investigate.

Is there any chance you’re able to access %t.v1.o, %t.v2.o, and/or %t.exe from the last failed run? That would be a big help (this certainly doesn’t reproduce on my system), but if not, no problem, I’ll set up a VM.

 // RUN: %clangxx_profgen -std=c++14 -fcoverage-mapping %s -c -o %t.v1.o \
 // RUN:                  -D_VERSION_1
 // RUN: %clangxx_profgen -std=c++14 -fcoverage-mapping %s -c -o %t.v2.o \
 // RUN:                  -D_VERSION_2
 // RUN: %clangxx_profgen -std=c++14 -fcoverage-mapping %t.v1.o %t.v2.o \
 // RUN:                  -o %t.exe
