[PATCH] D30886: [ELF] Pad x86 executable sections with 0xcc int3 instructions

jhenderson added a comment.

I measured the size difference in the before and after links of lld and clang when compressed using gzip:

lld uncompressed size before = 873234440
lld uncompressed size after = 873242664
lld compressed size before = 256393477
lld compressed size after = 256389682
lld compression ratio before (compressed/uncompressed) = 29.3614%
lld compression ratio after = 29.3606%

clang uncompressed size before = 1608322256
clang uncompressed size after = 1608322256
clang compressed size before = 456620551
clang compressed size after = 456595069
clang compression ratio before = 28.3911%
clang compression ratio after = 28.3895%

So interestingly, the compression actually improves fractionally with this patch.
