Benjamin Saunders b0d0b1adfe clang_6: fix sanitizers under libstdc++ 2018-05-24 15:04:30 -07:00

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

Also fix some setup hooks that unnecessarily used environment hooks,
which revolted in the same variable being modified too many times.

Jan Malakhovski 82dd4501f4 bintools-wrapper, cc-wrapper: don't add targetPrefix the second time 
... binutils and gcc add it already anyway.

Without this it's easy to get cross-toolchain paths longer than 256
chars and nix-daemon will then fail to commit them to /nix/store on XFS.

hardening: clarify the whitelist logic 
Per @Ericson2314's suggestion [1], make it more clear that the active
hardenings are decided via whitelist; the blacklist is merely for the
debug messages.

hardening: fix careless bugs 
I got a substitution backwards (used '+' instead of '-').

Also, this now works under `set -u` (had to fix a couple unbound
variable references).

Nikolay Amiantov 9a9c2e6579 cc-wrapper: fix bool handling for empty and zero values 
Before the code would fail silently for zero values and with some output for
empties. We now currently handle both via defaulting value to zero and making
`let` return success error code when there's no syntax error.

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 3a50395ef2 {bintools,cc}-wrapper: extraPackages should be depsTargetTargetPropagated 
They are libraries used by programs built with these tools, not used by the
tools themselves.

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.

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 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.

John Ericson bdd6c037c0 cc-wrapper: Use separate mangler for "bool" variables

It need not concern itself with 32-bit dynamic linking; ld-wrapper handles that now.

Will Dietz 115bf9d2cf cc-wrapper: don't add broken cflags to clang 
On non-GNU (gcc) compilers, there is no "/lib/gcc/..."
so when this is eventually expanded this is empty
resulting in an incomplete "-idirafter " that
eats the next argument:

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.
