John Ericson 0aee847858 cc-wrapper: Make the cross compiler use a crossEnvHook
This is a hack until stdenv's setup.hs gets overhauled
2017-06-22 17:52:29 -04:00
Ross MacLeod c1fb71b74a cc-wrapper: when cross building, wedge in setting AR, AS, and LD env vars to their cross building versions
I think it's ok to export things which aren't wrapped. The cc-wrapper
can be thought of as responsible for all of binutils and the c
compiler, only wrapping those binaries which are necessary to
interposition---as opposed to all binaries it thinks are relevaant.

Conversely, adding the setup hook to the unwrapped compilers would be
unforunate as hooks are ugly hacks and the compilers themselves take
a long time to rebuild. Better to wholely separate "pure packages" from
hacks.

John Ericson 8a7433fca4 cc-wrapper: Temporarily got to great lengths to avoid mass-rebuild
Eventually we should avoid this "pre-wrapping" and just update those
files in nixpkgs. This mass-rebuild change is best done along with
those needed to reduce the disparity between native and cross (i.e.
making native the "identity cross").

John Ericson 0f0383394d cc-wrapper: Salt environment variables with LLVM triples
We now (on cross) require per-target flag interposition by putting the
triple in the names of the relevant environment variables, e.g:

export NIX_arm_unknown_linux_gnu_CFLAGS_COMPILE=...

The wrapper also has a `infixSalt` attribute (and "_" prefixed and
suffixed variants) to assist downstream packages.

Note how that the dashes are replaced to keep the identifier valid.
Using names like this allows us to keep the settings for different
compilers seperate.

I think it might be even better to use names like `NIX_{BUILD,HOST}...`
using the platform's role rather than the platform itself, but this
would be more work as the previous stages' tools would have to be re-
wrapped to take on their new role. I therefore didn't do this for now,
but that route should be thoroughly explored in the future.

cc-wrapper: externalize default_cxx_stdlib_compile
This value is require to get c++ std include path for libclang based tools (vim plugins in my case).
I currently extract it this with this rather command:

```
eval echo $(nix-instantiate --eval --expr 'with (import <nixpkgs>) {}; clang.default_cxx_stdlib_compile')
```

it did not trigger any recompilation on my system.

Franz Pletz aff1f4ab94 Use general hardening flag toggle lists
The following parameters are now available:

  * hardeningDisable
    To disable specific hardening flags
  * hardeningEnable
    To enable specific hardening flags

Only the cc-wrapper supports this right now, but these may be reused by
other wrappers, builders or setup hooks.

cc-wrapper supports the following flags:

  * fortify
  * stackprotector
  * pie (disabled by default)
  * pic
  * strictoverflow
  * format
  * relro
  * bindnow

Anthony Cowley d96893647d cc-wrapper: fix on darwin
The ld-wrapper.sh script calls `readlink` in some circumstances. We need
to ensure that this is the `readlink` from the `coreutils` package so
that flag support is as expected.

This is accomplished by explicitly setting PATH at the top of each shell
script.

Without doing this, the following happens with a trivial `main.c`:

```
nix-env -f "<nixpkgs>" -iA pkgs.clang
$ clang main.c -L /nix/../nix/store/2ankvagznq062x1gifpxwkk7fp3xwy63-xnu-2422.115.4/Library -o a.out
readlink: illegal option -- f
usage: readlink [-n] [file ...]
```

The key element is the `..` in the path supplied to the linker via a
`-L` flag. With this patch, the above invocation works correctly on
darwin, whose native `/usr/bin/readlink` does not support the `-f` flag.

The explicit path also ensures that the `grep` called by `cc-wrapper.sh`
is the one from Nix.

Vladimír Čunát efcad4c910 gcc5: split $doc into $man and $info

Eelco Dolstra 6671bb8be4 Remove gccStdInc
This reverts d927da8dae. Having a copy
of gcc-wrapper/setup-hook.sh is bad for maintainability - it had
already started to diverge. Also, gccStdInc gave a nix-env conflict
with the standard gcc. And it wasn't actually used in Nixpkgs.

Instead, if you really need to change "-isystem" to "-I", you can now
set ccIncludeFlag to "-I".

Vladimír Čunát d484c392aa stdenv multiple-outputs: change propagation rules
