A DISubprogram on x86_64 was 48 bytes. During an LTO build we end up allocating *a lot* of these (see Duncan's numbers on llvm-dev and/or my numbers in the review link). This change reduces the size to 40 bytes, with a nice effect on peak memory usage when LTO'ing clang. There are more classes in the hierarchy which can be compacted so more patches will come. DISubprogram was the biggest offender in my profiling, anyway. Differential Revision: http://reviews.llvm.org/D18918 llvm-svn: 266241 |
