From 68d83fae70b2fa136b6c4a8c91af9e615eeedf95 Mon Sep 17 00:00:00 2001 From: Yi Kong Date: Sun, 29 Jun 2025 10:37:12 +0800 Subject: [PATCH] [llvm-profdata] Resolve tilde for weighted input filenames (#146206) When specifying a weighted input file, the shell does not automatically expand the tilde (`~`) character in the filename because the argument is passed as a single string in the format `,`. This commit fixes the issue by using `llvm::sys::fs::expand_tilde` to explicitly resolve the tilde in the filename, ensuring that paths like `~/path/to/file` are correctly handled. --- llvm/tools/llvm-profdata/llvm-profdata.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/llvm/tools/llvm-profdata/llvm-profdata.cpp b/llvm/tools/llvm-profdata/llvm-profdata.cpp index a7cbd4bfc838..45eac90aef93 100644 --- a/llvm/tools/llvm-profdata/llvm-profdata.cpp +++ b/llvm/tools/llvm-profdata/llvm-profdata.cpp @@ -1705,7 +1705,10 @@ static WeightedFile parseWeightedFile(const StringRef &WeightedFilename) { if (WeightStr.getAsInteger(10, Weight) || Weight < 1) exitWithError("input weight must be a positive integer"); - return {std::string(FileName), Weight}; + llvm::SmallString<128> ResolvedFileName; + llvm::sys::fs::expand_tilde(FileName, ResolvedFileName); + + return {std::string(ResolvedFileName), Weight}; } static void addWeightedInput(WeightedFileVector &WNI, const WeightedFile &WF) {
