| * BinUtils: Avoid llvm-mt because it is missing 'mt' features we useBrad King2022-03-081-1/+2
|/ | | | | | | | | | Since commit cf82300a63 (BinUtils: Clarify search logic and make it more consistent, 2021-05-27, v3.21.0-rc1~119^2~2) we correctly prefer the more-specific name `llvm-mt` over `mt` when using Clang. However, the `llvm-mt` tool does not yet support all the flags we need in the implementation of `vs_link_{exe,dll}`. Prefer plain `mt` for now. Fixes: #23305

|/ | | | | | | | | | Since commit cf82300a63 (BinUtils: Clarify search logic and make it more consistent, 2021-05-27, v3.21.0-rc1~119^2~2) we correctly prefer the more-specific name `llvm-ar` over `ar` when using Clang. However, on Apple platforms, `llvm-ar` does not generate a symbol table that the Apple linker accepts. Fall back to `ar` on Apple platforms. Fixes: #23269

| * FindThreads: Revert "Honor THREADS_PREFER_PTHREAD_FLAG when ... in libc"Brad King2022-02-281-11/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert commit 5efb6fb516 (FindThreads: Honor THREADS_PREFER_PTHREAD_FLAG when pthread is found in libc, 2021-11-03, v3.21.5~4^2). The check for the `-pthread` flag can pass on compilers like XL, that interprets it as `-p -t hread` and returns zero. Prior to that commit, we did not use the check in the `CMAKE_HAVE_LIBC_PTHREAD` code path. Now we do, it succeeds, and we incorrectly add the `-pthread` flag for XL. This change was backported to the 3.21 and 3.22 release series long after they initially came out. Since there may be more cases where we now add `-pthread` incorrectly, it is simplest to revert the change in all release series pending further investigation. Fixes: #23270

Those flags were added by commit a624a3e1b3 (Ninja: Use deps=gcc for Intel Compiler on Windows, 2019-01-30, v3.14.0-rc1~30^2), which forgot to account for commit 6d74e7870b (Ninja: Add dependencies on system-provided header files, 2016-03-15, v3.6.0-rc1~265^2). The `-QMD` option generates Makefile dependencies. The `-QMMD` option generates Makefile dependencies, but excludes system header files. Part of the BuildDepends test includes a header, cmake_pch.hxx, that includes a second header, zot_pch.hxx. The test builds a pch file for cmake_pch.hxx, touches zot_pch.hxx, then verifes that cmake_pch.hxx.pch is regenerated based on the dependencies. The cmake_pch.hxx contains `#pragma system_header` before it includes zot_pch.hxx. `#pragma system_header` indicates that the portion of the file following the pragma is to be treated as a system header. When `-QMMD` is used to generate dependencies, the `#include` of zot_pch.hxx is ignored because it `-QMMD` says to ignore system headers. Using `-QMD` instead uses all headers when generating dependencies and causes this test to pass. The Clang configuration in Platform/Windows-Clang.cmake also uses the `-MD` option for generating pre-compiled headers, instead of `-MMD`. Signed-off-by: William R.

This was probably due to misinterpreting the change from commit 7975edeac5 (Help: User-provided variable names for try_* commands, 2019-02-24, v3.14.0-rc3~16^2~3). The result variable has never been fixed. Drop the incorrect markup.

| * | message: Restore explicit flushing of messages on stderrBrad King2022-01-271-2/+2
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the `cmake` command-line tool, the `message()` command with no message mode argument prints the message stderr using the C++ `cerr` stream. Since commit 0a0a0f8a74 (cmMessenger: Color messages to terminal by type, 2021-05-18, v3.21.0-rc1~146^2) and an update by commit c7a8c9c811 (cmMessenger: Revert to non-color messages on Windows, 2021-07-20, v3.21.1~15^2), we print the newline at the end of the message using just `\n`. We've now observed some cases of output on stdout and stderr getting jumbled when the two go to the same file descriptor. Previously the newline was printed with `endl`, which implicitly flushes. Flush explicitly to restore that behavior. Fixes: #23155

| | | | | | | | | | | | | | | | | | | | | | | | The `-pthread` flag tells the compiler/linker to link to additional libraries needed for thread support (e.g. libatomic on riscv64). The flag therefore should be used if requested using `THREADS_PREFER_PTHREAD_FLAG` also when the pthread functions are found in libc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit f3f57cc4ed (NMake: Use UTF-8 with BOM if supported by nmake, 2021-04-22, v3.21.0-rc1~217^2), we add a BOM to response files to tell MSVC tooling that they are encoded as UTF-8. However, the "NMake Makefiles" generator may also be used with non-MSVC toolchains that do not understand the BOM. Update the response file encoding selection heuristic to add the BOM only with MSVC tooling. Fixes: #23143

|/ / | | | | | | | | | | | | | | Since commit f3f57cc4ed (NMake: Use UTF-8 with BOM if supported by nmake, 2021-04-22, v3.21.0-rc1~217^2) the encoding of response files is selected based on the makefile encoding. In principle these may be orthogonal, but in practice it is a useful heuristic. Call out this heuristic in a comment, and leave a FIXME to do something better.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | The logic added by commit 7808cbd644 (CMakeDetermineCompilerId: support Intel DPC++ compiler toolset for VS gen, 2020-12-06, v3.20.0-rc1~330^2) matches a specific toolset known to be the `icx.exe` compiler, and assumes all other Intel C++ compilers (that are not DPC++) must be `icl.exe`. Since `icx.exe` is officially replacing `icl.exe`, use a regex that matches the now-fixed set of toolsets known to use `icl.exe`. Any other Intel C++ compiler will be assumed to be `icx.exe`.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | The Intel compiler (pre-LLVM) expected xilink.exe and had special logic to set xilink.exe. The newer LLVM-based compiler does not want xilink.exe. link.exe works better for host code, and is the default, so change the matching condition such that the old compiler matches (and gets xilink.exe) and the new compiler gets the default link.exe it expects. A better solution will be to use the compiler as the linker. A future change will switch to compiler as linker by default, but that fix needs more validation. Signed-off-by: William R.
