[ELF][AsmPrinter] Emit trailing dot for constant pool section when it has a hotness prefix (#150859) 2025-07-30T00:04:59+00:00 Mingming Liu mingmingl@google.com 2025-07-30T00:04:59+00:00 277bcf7ffc79e7d8652dc2c89ce79535b405635a Currently, `TargetLoweringObjectFileELF::getSectionForConstant` produce `.<section>.hot` or `.<section>.unlikely` for a constant with non-empty section prefix. This PR changes the implementation add trailing dot when section prefix is not empty, to disambiguate `.hot` as a hotness prefix from `.hot` as a (pure C) variable name. Relevant discussions are in https://github.com/llvm/llvm-project/pull/148985#discussion_r2221141273 and https://github.com/llvm/llvm-project/pull/148985#discussion_r2233382641 and
