>From 4a30a862b41aa6c570b0dc4d1eb82a7feef4ed8e Mon Sep 17 00:00:00 2001 From: Dan McGregor <dan.mcgre...@usask.ca> Date: Mon, 14 Aug 2023 18:44:08 -0600 Subject: [PATCH 1/2] Support: hoist lld's executable name code to Path Instead of using custom code to find the program name throughout the codebase, write one function as a path helper to consistently determine the program name. This globally correctly finds target names with dots in them (ie freebsd13.2). --- lld/COFF/Driver.cpp | 2 +- lld/Common/Args.cpp | 6 ------ lld/ELF/Driver.cpp | 2 +- lld/MachO/Driver.cpp | 2 +- lld/include/lld/Common/Args.h | 2 -- lld/wasm/Driver.cpp | 2 +- lldb/tools/driver/Driver.cpp | 2 +- llvm/include/llvm/Support/Path.h | 15 +++++++++++++++ llvm/lib/Support/Path.cpp | 7 +++++++ llvm/tools/llvm-ar/llvm-ar.cpp | 3 ++- llvm/tools/llvm-cov/llvm-cov.cpp | 2 +- llvm/tools/llvm-driver/llvm-driver.cpp | 2 +- llvm/tools/llvm-objcopy/llvm-objcopy.cpp | 2 +- llvm/tools/llvm-objdump/llvm-objdump.cpp | 2 +- llvm/tools/llvm-rc/llvm-rc.cpp | 2 +- llvm/tools/llvm-readobj/llvm-readobj.cpp | 2 +- llvm/tools/llvm-symbolizer/llvm-symbolizer.cpp | 2 +- 17 files changed, 36 insertions(+), 21 deletions(-) diff --git a/lld/COFF/Driver.cpp b/lld/COFF/Driver.cpp index d7476e91e03e384..03a63bf3a306b4d 100644 --- a/lld/COFF/Driver.cpp +++ b/lld/COFF/Driver.cpp @@ -68,7 +68,7 @@ bool link(ArrayRef<const char *> args, llvm::raw_ostream &stdoutOS, auto *ctx = new COFFLinkerContext; ctx->e.initialize(stdoutOS, stderrOS, exitEarly, disableOutput); - ctx->e.logName = args::getFilenameWithoutExe(args[0]); + ctx->e.logName = sys::path::program_name(args[0]); ctx->e.errorLimitExceededMsg = "too many errors emitted, stopping now" " (use /errorlimit:0 to see all errors)"; diff --git a/lld/Common/Args.cpp b/lld/Common/Args.cpp index 48c934df3a2c931..b02d023fe19aeb5 100644 --- a/lld/Common/Args.cpp +++ b/lld/Common/Args.cpp @@ -85,9 +85,3 @@ std::vector<StringRef> lld::args::getLines(MemoryBufferRef mb) { } return ret; } - -StringRef lld::args::getFilenameWithoutExe(StringRef path) { - if (path.ends_with_insensitive(".exe")) - return sys::path::stem(path); - return sys::path::filename(path); -} diff --git a/lld/ELF/Driver.cpp b/lld/ELF/Driver.cpp index 9d167293574fa64..957d0da1589caf8 100644 --- a/lld/ELF/Driver.cpp +++ b/lld/ELF/Driver.cpp @@ -143,7 +143,7 @@ bool link(ArrayRef<const char *> args, llvm::raw_ostream &stdoutOS, SharedFile::vernauxNum = 0; }; - ctx->e.logName = args::getFilenameWithoutExe(args[0]); + ctx->e.logName = sys::path::program_name(args[0]); ctx->e.errorLimitExceededMsg = "too many errors emitted, stopping now (use " "--error-limit=0 to see all errors)"; diff --git a/lld/MachO/Driver.cpp b/lld/MachO/Driver.cpp index 00ff3439a043be9..ed0b66d4b2ec6ba 100644 --- a/lld/MachO/Driver.cpp +++ b/lld/MachO/Driver.cpp @@ -1428,7 +1428,7 @@ bool link(ArrayRef<const char *> argsArr, llvm::raw_ostream &stdoutOS, InputFile::resetIdCount(); }; - ctx->e.logName = args::getFilenameWithoutExe(argsArr[0]); + ctx->e.logName = sys::path::program_name(argsArr[0]); MachOOptTable parser; InputArgList args = parser.parse(argsArr.slice(1)); diff --git a/lld/include/lld/Common/Args.h b/lld/include/lld/Common/Args.h index 60f83fbbbf1a3c9..8822707a6a1f212 100644 --- a/lld/include/lld/Common/Args.h +++ b/lld/include/lld/Common/Args.h @@ -38,8 +38,6 @@ uint64_t getZOptionValue(llvm::opt::InputArgList &args, int id, StringRef key, std::vector<StringRef> getLines(MemoryBufferRef mb); -StringRef getFilenameWithoutExe(StringRef path); - } // namespace args } // namespace lld diff --git a/lld/wasm/Driver.cpp b/lld/wasm/Driver.cpp index c2f5f0185781f36..f13aa520f35b100 100644 --- a/lld/wasm/Driver.cpp +++ b/lld/wasm/Driver.cpp @@ -89,7 +89,7 @@ bool link(ArrayRef<const char *> args, llvm::raw_ostream &stdoutOS, auto *ctx = new CommonLinkerContext; ctx->e.initialize(stdoutOS, stderrOS, exitEarly, disableOutput); - ctx->e.logName = args::getFilenameWithoutExe(args[0]); + ctx->e.logName = sys::path::program_name(args[0]); ctx->e.errorLimitExceededMsg = "too many errors emitted, stopping now (use " "-error-limit=0 to see all errors)"; diff --git a/lldb/tools/driver/Driver.cpp b/lldb/tools/driver/Driver.cpp index f8058f868d53ffe..2fb760ca97a001d 100644 --- a/lldb/tools/driver/Driver.cpp +++ b/lldb/tools/driver/Driver.cpp @@ -754,7 +754,7 @@ int main(int argc, char const *argv[]) { ArrayRef<const char *> arg_arr = ArrayRef(argv + 1, argc - 1); opt::InputArgList input_args = T.ParseArgs(arg_arr, MissingArgIndex, MissingArgCount); - llvm::StringRef argv0 = llvm::sys::path::filename(argv[0]); + llvm::StringRef argv0 = llvm::sys::path::program_name(argv[0]); if (input_args.hasArg(OPT_help)) { printHelp(T, argv0); diff --git a/llvm/include/llvm/Support/Path.h b/llvm/include/llvm/Support/Path.h index ce69f32b6cc81ba..6dc0fa79031852e 100644 --- a/llvm/include/llvm/Support/Path.h +++ b/llvm/include/llvm/Support/Path.h @@ -390,6 +390,21 @@ StringRef stem(StringRef path, Style style = Style::native); /// @result The extension of \a path.
