Our gcc_multi and glibc_multi expressions merge together a
32-bit-targeted and 64-bit-targeted gcc. However they do not thread
through the passthru.libgcc from these merged gccs.
This commit corrects that.
It also extends passthru.libgcc to allow a *list* rather than just a
single outpath.
Resolves part of #221891 (at least getting it back to the error
message it gave before).
While searching for something different I wondered why there is a
trivial-builders.nix file next to the trivial-builders directory where
only tests live. Lets fix that.
LLD supports Windows-style linker arguments, but these previously
triggered purity check false positives, because it saw that they
started with a '/' and assumed they were paths.
This tweaks the path detection to allow through certain values that
could be paths, but are much more likely to be LINK.EXE-style flags.
The risk of false negatives here is low — the only things we'd now
fail to catch would be attempts to link with libraries in the root
directory, which doesn't happen in practice.
We also teach the wrapper how to apply its purity checks to library
paths specified with the /LIBPATH: option.
Tested that paths we expect to be rejected (like /lib/libfoo.so) still
are.
v1 lockfiles can contain multiple references to the same version of a
package, and these references can contain different `integrity` values,
such as one having SHA-1 and SHA-512, while another just has SHA-512.
Given that HashMap iteration order isn't defined, this causes
reproducibility issues, as a different integrity value could be chosen
each time.
Thanks to @lilyinstarlight for discovering this issue originally, as well
as the idea for the sorting-based implementation.
According to <https://gcc.gnu.org/legacy-ml/gcc-patches/2015-08/msg00836.html>,
all code is position-independent on Windows. Some compilers
apparently warn for -fPIC on Windows, and clang errors:
> clang-15: error: unsupported option '-fPIC' for target 'x86_64-pc-windows-msvc'
I'm guessing the check was hostPlatform instead of targetPlatform by mistake.
In f8ee061247, the fallback installPhase
if fFetchAttrs.installPhase is not provided, became dynamically computed.
Due to operator precedence this had the side effect of appending to
fFetchAttrs.installPhase if it is provided, breaking custom
installPhases altogether.
rustc supports way more platforms than Linux and Darwin. We might not
be able to build it for every platform at the moment, but that's what
meta.broken is for.
There are other platforms that rustc can produce binaries for, but
can't run on itself, so those are listed in the defaults for
buildRustPackage.
If multiple files with the same build id were found, we silently randomly
overwrote one with the other.
Change the order to make the output deterministic, and emit a
warning when overwriting.
