This patch adds statistics about the contribution of each object file to the linked debug info. When --statistics is passed to dsymutil, it prints a table after linking as illustrated below. It lists the object file name, the size of the debug info in the object file in bytes, and the absolute size contribution to the linked dSYM and the percentage difference. The table is sorted by the output size, so the object files contributing the most to the link are listed first. .debug_info section size (in bytes) ------------------------------------------------------------------------------- Filename Object dSYM Change ------------------------------------------------------------------------------- basic2.macho.x86_64.o 210b 165b -24.00% basic3.macho.x86_64.o 177b 150b -16.51% basic1.macho.x86_64.o 125b 129b 3.15% ------------------------------------------------------------------------------- Total 512b 444b -14.23% ------------------------------------------------------------------------------- Differential revision: https://reviews.llvm.org/D79513 |
