Tuomas Tynkkynen a06a405d0b cross GCC: Fix some paths to libc headers (after multiple outputs) 
It's not completely clear to me why the path to libc headers is set
differently when cross building...

Vladimír Čunát 2cbb7bf9d1 cc-wrapper: add -B flag with cc.lib 
This fixes `gcc --print-file-name=libstdc++.so`
and thus it should fix #14967.

Vladimír Čunát d1df28f8e5 Merge 'staging' into closure-size 
This is mainly to get the update of bootstrap tools.
Otherwise there were mysterious segfaults:

Vladimír Čunát ab15a62c68 Merge branch 'master' into closure-size 
Beware that stdenv doesn't build. It seems something more will be needed
than just resolution of merge conflicts.

Robin Gloster a9b942c061 cc-wrapper: treat hardeningDisable as string 
This fixes passing the env variable to the ld-wrapper through the gcc
call. Wtf?!

Vladimír Čunát 09af15654f Merge master into closure-size 
The kde-5 stuff still didn't merge well.
I hand-fixed what I saw, but there may be more problems.

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

Eelco Dolstra d5bb6a1f9c glibc: Enable separate debug symbols 
The importance of glibc makes it worthwhile to provide debug
symbols. However, this revealed an issue with separateDebugInfo: it
was indiscriminately adding --build-id to all ld invocations, while in
fact it should only do that for final links. Glibc also uses non-final
("relocatable") links, leading to subsequent failure to apply a build
ID ("Cannot create .note.gnu.build-id section, --build-id
ignored"). So now ld-wrapper.sh only passes --build-id for final
links.

Eelco Dolstra 2040a9ac57 stdenv-linux: Ensure binutils comes before bootstrapTools in $PATH 
Otherwise, when building glibc and other packages, the "strip" from
bootstrapTools is used, which doesn't recognise some tags produced by
the newer "ld" from binutils.

Vladimír Čunát 96cbdc70f2 cc-wrapper: fix #10574: old gcc -> cc fallout 
The part with gcc-wrapper-old changes is rather unimportant,
as it's almost unused but I still tested that the sole user `gnat` builds.

Vladimír Čunát f89a136fd5 cc-wrapper: fixup branch interactions 
c0599fdd61 and changes on closure-size didn't go well together.
 2016-02-03 16:57:41 +01:00
Vladimír Čunát ae74c356d9 Merge recent 'staging' into closure-size 
Let's get rid of those merge conflicts.

Vladimír Čunát a33fcc8731 cc-wrapper: attempt to fix on darwin 
This fixes evaluation at least. I'm unable to test this myself and noone steps up;
https://github.com/NixOS/nixpkgs/pull/7701#issuecomment-174448705
however, Hydra's macs are idling so let's employ them for that.

Vladimír Čunát 8f48a9756b cc-wrapper: quote when saving $PATH 2016-01-25 09:54:10 +01:00
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.

Fixes #6447
