Revert "bintools-wrapper: skip dynamic linker for static binaries" 
This reverts commit ccfd26ef14.

These toolchain changes are too problematic, so reverting for now; see
https://github.com/NixOS/nixpkgs/pull/107086#issuecomment-749196366

Jörg Thalheim ccfd26ef14 bintools-wrapper: skip dynamic linker for static binaries 
Currently we set dynamic-linker unconditionally. This breaks
however some static binaries i.e. rust binaries linked against musl.
There is no reason we should set an elf interpreter for static binaries
hence this is skipped if `-static` or `-static-pie` is either passed to
our cc or ld wrapper.

stdenv: make -nostdinc work as intended 
Right now we add glibc to search path also -nostdinc was provided,
which breaks projects providing their own gcc.

John Ericson 1ac5398589 *-wrapper; Switch from infixSalt to suffixSalt 
I hate the thing too even though I made it, and rather just get rid of
it. But we can't do that yet. In the meantime, this brings us more
inline with autoconf and will make it slightly easier for me to write a
pkg-config wrapper, which we need.

Craig Hall 0b7494ed2b cc-wrapper: add (partial) support for clang -cc1

Matthew Bauer d180cb9850 cc-wrapper: make machine configuration configurable 
It is useful to make these dynamic and not bake them into gcc. This
means we don’t have to rebuild gcc to change these values. Instead, we
will pass cflags to gcc based on platform values. This was already
done hackily for android gcc (which is multi-target), but not for our
own gccs which are single target.

To accomplish this, we need to add a few things:

- add ‘arch’ to cpu
- add NIX_CFLAGS_COMPILE_BEFORE flag (goes before args)
- set -march everywhere
- set mcpu, mfpu, mmode, and mtune based on targetPlatform.gcc flags

cc-wrapper: only set -march when it is in the cpu type

Some architectures don’t have a good mapping of -march. For instance
POWER architecture doesn’t support the -march flag at all!

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.

John Ericson 4f869bccc1 cc-wrapper: Don't treat "-" alone as a flag 
It means stdin, and is morally equivalent to passing a file. e.g.

  $ echo 'int main(void) { return 0; }' | gcc -x c -

will compile and link a binary.

It's better layering to do everything in ld-wrapper. Also, use numeric

Revert "Merge pull request #28557 from obsidiansystems/binutils-wrapper" 
This reverts commit 0a944b345e, reversing
changes made to 61733ed6cc.

I dislike these massive stdenv changes with unclear motivation,
especially when they involve gratuitous mass renames like NIX_CC ->
NIX_BINUTILS. The previous such rename (NIX_GCC -> NIX_CC) caused
months of pain, so let's not do that again.

John Ericson 822a8d0148 cc-wrapper: Remove redundant hardening 
GCC just passes `-z ...` flags to ld unaltered, and they are already
passed to LD anyways. On the other hand, `-pie` affects gcc behavior
too.

John Ericson 2493454e13 cc-wrapper: Use set -u throughout 
Now is an opportune time to do this, as the infixSalt conversion in
`add-flags.sh` ensures that all the relevant `NIX_*` vars will be
defined even if empty.

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`
 2017-08-07 03:05:50 -04:00
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.

cc-wrapper/ld-wrapper: Minor speedup in string concatenation 
There is still a O(n) pattern match in ld-wrapper, so we should
probably rewrite that code to use associative arrays.
