assembly file generated from test.c with x86_64-w64-mingw32-gcc

Find attached the file test-gcc.s (compressed with xz). It was generated with
the command x86_64-w64-mingw32-gcc -fdata-sections -S test.c -o test-gcc.s

If you use x86_64-w64-mingw32-as, it will give you the "file too big" error
message.

Please clarify. I already uploaded test-llvm.o. It contains plenty of //BASE64
names. Currently llvm is currently the only toolchain that allows me to create
such a file. Is that sufficient?
