Mips architectures may have `el` on the end, to differentiate the little
endian from the big endian variants. We don't encode endianness in the
cpu names, so ensure we've stripped that.

Fixes: c708c52ca2 ("linkers: Update the linker names to be more consistent")
Emscripten does have a stand alone linker, wasm-ld. This patch adds the
linker, adds detection for the linker, and removes the IsLinkerMixin for
emscripten. This is a little more correct, and makes the code a lot
cleaner and more robust.
This is more correct, and forces the target(s) to be rebuilt if the
PDB files are missing. Increases the minimum required Ninja to 1.7,
which is available in Ubuntu 16.04 under backports.
We can't do the same for import libraries, because it is impossible
for us to know at configure time whether or not an import library will
be generated for a given DLL.
This makes two basic changes, 1 it moves the name of the linker into the
linker class, this should reduce the number of errors and typos, and
ensure that a linker always has one name. This then renames the linkers
to have more consistent names.
Posix/gnu linkers are called ld.<name>: ld.gold, ld.lld, ld.solaris.
Apple linkers are renamed ld64.
This allows Meson native-file [properties] to be used.
This avoids the need to call meson from a script file or have a
long command line invocation of `meson setup`
The method meson.get_native_property('prop', 'fallback') is added.
The native file can contain properties like
```
[properties]
myprop1 = 'foo'
mydir2 = 'lib/custom'
```
Then from within `meson.build`
```meson
x1 = meson.get_native_property('myprop1')
thedir = meson.get_native_property('mydir2', 'libs')
```
fallback values are optional
The rust code is ugly, because rust is annoying. It doesn't invoke a
linker directly (unless that linker is link.exe or lld-link.exe),
instead it invokes the C compiler (gcc or clang usually) to do it's
linking. Meson doesn't have good abstractions for this, though we
probably should because some of the D compilers do the same thing.
Either that or we should just call the c compiler directly, like vala
does.
This changes the public interface for meson, which we don't do unless we
absolutely have to. In this case I think we need to do it. A fair number
of projects have already been using 'ld' in their cross/native files to
get the ld binary and call it directly in custom_targets or generators,
and we broke that. While we could hit this problem again names like
`c_ld` and `cpp_ld` are far less likely to cause collisions than `ld`.
Additionally this gives a way to set the linker on a per-compiler basis,
which is probably in itself very useful.
Fixes#6442
* environment: Fix passing always args to a number of less common linkers
These are mostly (oops xilink) proprietary linkers I can't use for
various reasons.
Fixes: #6332
* Add intelfix from scivision.
* Ifort fix from scivision.
* PGI fix from scivision.
* Cuda fix from scivision.
* Fix linker passing for armclang.
If a user passes -fuse-ld=gold to gcc or clang, they expect that they'll
get ld.gold, not whatever the default is. Meson currently doesn't do
that, because it doesn't pass these arguments to the linker detection
logic. This patch fixes that. Another case that this is needed is with
clang's --target option
This is a bad solution, honestly, and it would be better to use $LD or a
cross/native file but this is needed for backwards compatability.
Fixes#6057
This dumps xild on mac and linux. After a lot of reading and banging my
head I've discovered we (meson) don't care about xild, xild is only
useful if your invoke ld directly (not through icc/icpc) and you want to
do ipo/lto/wpo. Instead just make icc report what it's actually doing,
invoking ld or ld64 (for linux and mac respectively) directly. This
allows us to get -fuse-ld working on linux.
Since I spent three days banging my head against this it seems
reasonable that other people might also run into this problem. It can
happen if you're trying to use microsoft's link.exe, but also have the
dmd bin directory at the tail of your %PATH%, among other reasons.
Since we pass the whole compiler class (as a type()) we don't need to
also pass it's LINKER_PREFIX attribute, we can just get it from the
type we're passing.
Rather than trying to figure out if we're using MSVC based on
environment variables, then trying to get the C compiler and test some
attributes, get the C compiler and see if it's MSVC. This is much more
reliable and we were already doing it anyway.
Since version 9.1, GCC provides support for the D programming language. Thus it
is easy to build a cross-compiler for D, such as aarch64-unknown-linux-gnu-gdc.
However to cross-compile a Meson project using D, using a cross build definition
such as the following is not enough:
```
[binaries]
d = '/path/to/aarch64-unknown-linux-gnu-gdc'
exe_wrapper = '/path/to/qemu-aarch64-static'
[properties]
needs_exe_wrapper = true
[host_machine]
system = 'linux'
cpu_family = 'aarch64'
cpu = 'cortex-a53'
endian = 'little'
```
Indeed, "exe_wrapper" is not be taken into account. Build will fail with:
```
Executables created by D compiler /path/to/aarch64-uknown-linux-gnu-gdc are not runnable.
```
This patch fixes this by reworking:
- detect_d_compiler() to properly get exe_wrapper and D compilers and detect the
one available.
- Dcompiler to properly handle exe_wrapper.
fixes regression for systems with nvcc installed--perhaps why not previously caught on CI.
Just a simple typo--missing a positional argument to CudaCompiler()
0c22798b1a is the first bad commit File
"meson\mesonbuild\environment.py", line 1066, in detect_cuda_compiler
return CudaCompiler(ccache + compiler, version, for_machine, is_cross, exe_wrap, host_compiler=cpp_compiler,

Now that the linkers are split out of the compilers this enum is
only used to know what platform we're compiling for. Which is
what the MachineInfo class is for
