CMP0141: Fix PCH REUSE_FROM when MSVC_DEBUG_INFORMATION_FORMAT is empty

2022-11-15T11:57:02+00:00

Under the policy's NEW behavior, `[CMAKE_]MSVC_DEBUG_INFORMATION_FORMAT`
may be explicitly set to an empty string to tell CMake not to add any
flags for this abstraction.  In this case, fall back to checking the
language-wide flags as we do in the OLD behavior.

This revises commit 183b9a9eca (CMP0141: Fix PCH REUSE_FROM under policy
NEW behavior, 2022-10-31, v3.25.0-rc3~4^2).

Issue: #24106

CMP0141: Fix PCH REUSE_FROM under policy NEW behavior

2022-10-31T16:19:06+00:00

Under the CMP0141 NEW behavior added by commit 0e96a20478 (MSVC: Add
abstraction for debug information format, 2022-08-25, v3.25.0-rc1~142^2~1),
the `-Zi` and `-ZI` flags do not appear in `CMAKE__FLAGS_`
anymore.  Teach the PCH REUSE_FROM implementation to recognize the
`EditAndContinue` and `ProgramDatabase` debug information formats
through the policy's new abstraction.

Fixes: #24106

Tests: Drop redundant project init from RunCMake.PrecompileHeaders cases

2022-10-31T16:17:29+00:00

The `CMakeLists.txt` file already calls `cmake_minimum_required` and
`project` before including each case's code.

LCC: Add dedicated support for MCST LCC compiler

2021-10-15T02:05:19+00:00

Divert LCC compiler as a new one, instead of treating it as GNU.

Since old times, Elbrus C/C++/Fortran Compiler (LCC) by MCST has been
passing checks for GNU compilers, so it has been identified as GNU.
Now, with intent of seriously upstreaming its support, it has been
added as a separate LCC compiler, and its version displays not a
supported GCC version, but LCC version itself (e.g. LCC 1.25.19 instead
of GNU 7.3.0).

This commit adds its support for detection, and also converts basically
every check like 'is this compiler GNU?' to 'is this compiler GNU or
LCC?'. The only places where this check is untouched, is where it
regards other platforms where LCC is unavailable (primarily non-Linux),
and where it REALLY differs from GNU compiler.

Note: this transition may break software that are already ported to
Elbrus, but hardly relies that LCC will be detected as GNU; still such
software is not known.

PCH: MSVC: Restrict OBJECT library INTERFACE_LINK_LIBRARIES usage

2021-09-15T14:39:46+00:00

The pch object file could cause problems when the reused pch is passed
through an OBJECT library, which would use INTERFACE_LINK_LIBRARIES to
link the pch object file.

VS: Restore support for PCH in CXX but not C within once target

2021-02-19T16:25:29+00:00

Fix logic from commit 9df1f33c9a (VisualStudio: move PCH rules to
projects when possible., 2020-10-15, v3.20.0-rc1~638^2) to explicitly
disable PCH on sources that should not use the target-wide PCH rules.
