There is a distinction to be made between the Haskell Preprocessor and
the C preprocessor. The former is used to preprocess Haskell files,
while the latter is used in C preprocessing such as Cmm files.
In practice, they are both the same program (usually the C compiler) but
invoked with different flags.
Previously we would, at configure time, configure the haskell
preprocessor and save the configuration in the settings file, but,
instead of doing the same for CPP, we had hardcoded in GHC that the CPP
program was either `cc -E` or `cpp`.
This commit fixes that asymmetry by also configuring CPP at configure
time, and tries to make more explicit the difference between HsCpp and
Cpp (see Note [Preprocessing invocations]).
Note that we don't use the standard CPP and CPPFLAGS to configure Cpp,
but instead use the non-standard --with-cpp and --with-cpp-flags.
The reason is that autoconf sets CPP to "$CC -E", whereas we expect the
CPP command to be configured as a standalone executable rather than a
command. These are symmetrical with --with-hs-cpp and
--with-hs-cpp-flags.
Cleanup: Hadrian no longer needs to pass the CPP configuration for CPP
to be C99 compatible through -optP, since we now configure that
into settings.
Closes #23422

ghc-toolchain: Rename readProcess to readProcessStdout
Fixes bugs regarding a translation from the original autconf program
that failed to account for the exit code.
The longer name reenforces that we really only care about the stdout,
and the exit code and stderr of the program are irrelevant for the case.
Fixes
Re-introduce ld-override option
ghc-toolchain library and usage in hadrian flags
Re-introduce flags in hadrian config
ghc-toolchain: UseLibFFI, LdCompactUnwind, LdFileList
A more complete ghc-toolchain.
Added configuration of:
* Use libffi for adjustors
* Supports compact unwind
* Supports filelist
Handle passing CPP cmd and flags from configure to ghc-toolchain
Rip more of configure that is no longer being used
Remove configure checks of GNUnoexecStack and ident directive
And fix bug in ghc-toolchain respective code
Rip out more from hadrians system.config.in
Configure CLink supports response files
Read deleted keys from host and target's target
Delete CMD_OPTS_STAGEX
Instead of having configure configure different options for different
programs depend on the stage, we delete this completely and have hadrian
select the correct target toolchain configuration file depending on the
stage, from which it can read those options.
Fix [host|target]-[os|arch] vs [host|target]-haskell-[os|arch]
Handle unspecified vs specified flags and commands better
Configure Cpp and HsCpp separately
Fixes for compilation
Link is GNU linkerg
Revert "Rip more of configure that is no longer being used"
I realized we still need this function in rts/configure.ac
This reverts commit 01f5d4b480f4ab1514ac0a4fc957db199d1a0279.
Revert get_arm_isa deletion from 74f03f243d08aa910d39cdd9dadb976e9386283a
As in the previous commit, we still need this info from the rts
configure script.
I suppose it could be useful for the rts to also read somehow the
toolchain information...
helper AC function for enable/disable
Delete unused imports of SysTools.Info
Drop PROG_CPP in distrib/autoconf too
Get rid of MonadCatch instances and dependencies
ghc-toolchain: Check Cc supports extra-via-c-flags
Consider empty programs as non-specified programs
Cpp and HsCpp cleanup
Add comment from check for gold t22266
Remove more settings bits from hadrian/cfg
Use llvm target from ghc-toolchain
Print default.target
Fix bugs in MergeTool and Ar
Add check and log errors on error
