Clang uses signext/zeroext attributes for integer arguments shorter than
the default 'int' type on a target. So Flang has to match this for functions
from Fortran runtime and also for BIND(C) routines. This patch implements
ABI adjustments only for Fortran runtime calls. BIND(C) part will be done
separately.
This resolves https://github.com/llvm/llvm-project/issues/58579

As an attempt to fix errors in Flang regression tests on RISCV64 platform, RISCV64 target was added, and subsequent tests were provided.

This allows all ELF operating systems to use target specifics tuned for Linux,
since they use mostly the same ABIs. If some triples are to excluded, it's
better done at the driver layer.

As described in Issue #57642, `flang` currently lacks SPARC support in
`Optimizer/CodeGen/Target.cpp`, which causes a considerable number of tests
to `FAIL` with
error: flang/lib/Optimizer/CodeGen/Target.cpp:310: not yet implemented:
target not implemented
This patch fixes this by following GCC`s documentation of the ABI described
in the Issue.
Tested on `sparcv9-sun-solaris2.11`.

When testing LLVM 15.0.0 rc1 on Solaris, I found that 50+ flang tests
`FAIL`ed with
error:
/vol/llvm/src/llvm-project/local/flang/lib/Optimizer/CodeGen/Target.cpp:310:
not yet implemented: target not implemented
This patch fixes that for Solaris/x86, where the fix is trivial (just
handling it like the other x86 OSes).
Tested on `amd64-pc-solaris2.11`; only a single failure remains now.

This patch basically extends https://reviews.llvm.org/D122008 with
support for MacOSX/Darwin.
To facilitate this, I've added `MacOSX` to the list of supported OSes in
Target.cpp. Flang already supports `Darwin` and it doesn't really do
anything OS-specific there (it could probably safely skip checking the
OS for now).
Note that generating executables remains hidden behind the
`-flang-experimental-exec` flag. Also, we don't need to add `-lm` on
MacOSX as `libm` is effectively included in `libSystem` (which is linked
in unconditionally).

This patch adds Win32 to the list of supported triples in
`fir::CodeGenSpecifics`. This change means that we can use the "native"
triple, even when running tests on Windows. Currently this affects only
1 test, but it will change once we start adding more tests for lowering
and code-generation.

This patch add conversion for primitive operations on complex types.
- fir.addc
- fir.subc
- fir.mulc
- fir.divc
- fir.negc
This adds also the type conversion for !fir.complex<KIND> type.
This patch is part of the upstreaming effort from fir-dev branch.
This patch was updated to avoid failure on windows buildbot.
Flang codegen does not support windows target so we force the test
to use a known target instead.

This patch adds the basic infrastructure for the TargetRewrite pass,
which rewrites certain FIR dialect operations into target specific
forms. In particular, it converts boxchar function parameters, call
arguments and return values. Other convertions will be included in
future patches.
