Ben Wolsieffer 645f03b949 cc-wrapper, bintools-wrapper: use getHostRoleEnvHook instead of getTargetRoleEnvHook

John Ericson 5e17335bd7 Merge remote-tracking branch 'upstream/staging' into strictDeps 2018-05-14 23:33:03 -04:00
John Ericson 330ca731e8 treewide: Get rid of all uses of crossConfig
The hack of using `crossConfig` to enforce stricter handling of
dependencies is replaced with a dedicated `strictDeps` for that purpose.
(Experience has shown that my punning was a terrible idea that made more
difficult and embarrising to teach teach.)

Now that is is clear, a few packages now use `strictDeps`, to fix
various bugs:

 - bintools-wrapper and cc-wrapper

Merge pull request #40139 from obsidiansystems/modular-setup-hooks
treewide: Modular setup hooks
2018-05-07 15:32:10 -04:00
John Ericson 2110c0bd30 treewide: Use pkgs/build-support/roles.bash to remove copy pasta
Also fix some setup hooks that unnecessarily used environment hooks,
which revolted in the same variable being modified too many times.

hardening: ld wrapper changes, setup-hook, etc 2018-03-06 19:21:10 -05:00
John Ericson 469fd89832 stdenv-setup: Ease the transition with native builds
- All deps go on the PATH

 - CC and Bintools wrappers with their host != depender's host still get their
   setup hooks run.

 - Environment hooks get applied to all packages

This isn't so elegent, but eases the transition on a very significant
PR.

John Ericson a036473a0a {bintools,cc}-wrapper: Fix setup hook to respect the role of the cc-compiler
We now have the information to properly determine the role the
cc-wrapper dependency has, by taking advantage of `offset`. No longer
use the soon-to-be-deprecated crossConfig environment variable, the
temp hack used before this change.
2017-12-30 22:04:21 -05:00
John Ericson 8e557ed2c5 bintools-wrapper: Init
Factor a bintools (i.e. binutils / cctools) wrapper out of cc-wrapper. While
only LD is wrapped, the setup hook defines environment variables on behalf of
other utilites.
2017-12-13 16:08:18 -05:00
John Ericson 43e1137397 cc-wrapper: Define new- and old-style cross env vars
For example, `BUILD_CC` and `CC_FOR_BUILD`
2017-11-28 15:57:05 -05:00
John Ericson f4cb1e2ffc cc-wrapper: Export env vars for objdump and readelf in setup-hook
Also fix alphabetical order
2017-11-28 15:56:21 -05:00
John Ericson 994cb76850 cc-wrapper: Don't leave CMD defined after setup hook
Rename to `cmd` too, as uppercase typically means the variable is
exported.

John Ericson 43e00f7d18 cc-wrapper: Fix stray binPrefix -> targetPrefix
I thought my sed in e755a8a27d was
exhaustive, but it was not.

cc-wrapper: don't export CPP
CPP defaults to $(CC) -E and setting it explicitly seems to cause
issues in a number of packages like gcc and gdb.

John Ericson 42f35503b5 cc-wrapper: Make hygienic
See the added comments for what exactly has been done.

John Ericson 9f1e009975 cc-wrapper: Unconditionally use @infixSalt@ accross the board
This is basically a sed job, in preparation of the next commit. The
rules are more or less:

  - s"NIX_(.._WRAPPER_)?([a-zA-Z0-9@]*)"NIX_\1@infixSalt@_\2"g

  - except for non-cc-wrapper-specific vars like `NIX_DEBUG`

John Ericson 6463fd3d7e cc-wrapper: Pass shellcheck and other cleanups
In many cases, this involved taking @orivej's and @edolstra's recent
ld-wrapper improvements, and applying then elsewhere.

John Ericson ea7d13cf1a stdenv-setup and misc hooks: Work with bash-3.4 for MacOS nix-shell
This is a temporary measure until this impurity is removed from Nix.

John Ericson 3739858571 cc-wrapper: Use new bash uppercase subsitution syntax in setup hook
While this requires newer bash, stdenv's setup.sh now does across the
board anyways. This way is more concise.

John Ericson 093cc00cdd cc-wrapper: Always export environment variables for binutils
Before, this only happened when cross compiling.

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.

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 5227fb1dd5 Merge commit staging+systemd into closure-size
Many non-conflict problems weren't (fully) resolved in this commit yet.

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 bf414c9d4f Merge 'staging' into closure-size
- there were many easy merge conflicts
- cc-wrapper needed nontrivial changes

Many other problems might've been created by interaction of the branches,
but stdenv and a few other packages build fine now.

Dan Peebles 7bea6aafae Some cc-wrapper changes to better support darwin and clang:
- Add a conditional flag for the c++ std lib
- Build binaries that get linked by our own dyld (someday)
- Automatically add framework directories in the setup hook

Shea Levy 7dc57a389e cc-wrapper: Set CC/CXX more specifically if possible 2015-01-16 10:50:53 -05:00
Eric Seidel 48f63c2f2e rename gcc-wrapper to cc-wrapper.
also makes cc-wrapper compatible with clang in the darwin fork.
