[BOLT] Make order of jump table successors deterministic When a jump table is recovered in postProcessIndirectBranches(), successors for the containing basic block are added in random order. Make the order deterministic. Reviewed By: yota9 Differential Revision: https://reviews.llvm.org/D119672 2022-02-14 10:37:20 -08:00

[BOLT][test] Replace /dev/null with temp file (#73485) NFC processing time script identifies tests by output filename. When `/dev/null` is used as output filename, we're unable to tell the source test, and the reports are unhelpful. Replace `/dev/null/` with `%t.null` which resolves the issue. 2023-11-27 10:53:18 -08:00			`RUN: llvm-bolt %t.exe --strict --print-cfg --print-only=main -o %t.null \`
