[GHC] #8683: add "cpp program" and "cpp program options" to settings file

I propose adding the following fields to the settings file: "use c compiler cpp", which can have either "YES" or "NO". If "YES", the settings file indicated C compiler is used unless the c compiler selection is overrided by ghc at runtime via -pgmc or -pgmp(p?) if "NO", then the "cpp program" and "cpp program options" fields would be used, unless overridden by -pgmp there'd be some associated patched in the compiler/main/DriverPipeline.hs too i think, but relatively minimal. this would make it much easier to distributed a GHC with its own CPP tool that works -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8683 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

RAWCPP_FLAGS = -undef -traditional ifeq "$(CC_CLANG_BACKEND)" "1" RAWCPP_FLAGS += -Wno-invalid-pp-token -Wno-unicode -Wno- trigraphs endif }}} which then in compiler/ghc.mk as part of the Config module has the line {{{ @echo 'cRAWCPP_FLAGS :: String'
$@ @echo 'cRAWCPP_FLAGS = "$(RAWCPP_FLAGS)"' $@ }}}
and then in compiler/main/SysTools.lhs we have {{{ let cpp_prog = gcc_prog cpp_args = Option "-E" : map Option (words cRAWCPP_FLAGS) ++ gcc_args }}} Interestingly, the -pgmP flag corresponds to {{{ sPgm_P = (cpp_prog, cpp_args), }}} and the optP flag is by default empty! {{{ sOpt_P = [] }}} so optP is meant for adding *additional* flags to cpp, but shouldn't be part of the default config, AND pgmP should be used to specify the full "cpp program and the prefix of args?" also currently it looks like cpp_args also passes in applicable gcc_args. (are there some examples of when thats used?!) theres probably some other things i'm overlooking, but thats the obvious stuff. I think I now understand enough to be able to cook up a strawman patch for this stuff, including the config time settings.in stuff, the piece that currently goes into the magic Config.hs hack that now should move into settings, and some of the dynflags / settings stuff. I'll try to hack it out tomorrow late afternoon. (though if someone beats me to it, they're welcome, i've never messed with autoconf before, though I think i can cargo cult write the correct changes there,) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8683#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I'm somehow not using the autconf quite correctly to properly instantiate the CPP cmd and CPP Flags fields of settings correctly. Some help would be appreciated! i've also done a test build where i by hand set {{{ ("Haskell CPP command","/Users/carter/bin/gcc"), ("Haskell CPP flags","-E -undef -traditional" ), }}} in my "settings" file after the configure step ran to validate the rest of the build process, and that works (ie testing that if i set it by hand, the new /DynFlags.hs etc logic behaves correctly). Namely that I manage to get stage2 to build correctly sooo, I think all thats left is figuring out what i'm doing wrong on the m4/ autoconf front -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8683#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

@trommler, hrmmmm
I was doing the command + flag design because that maps to the current GHC dynflags model, ... and I tried to set {{{gcc -E}}} for cpp and failed. GHC tries to exec {{{gcc -E}}} then and that does not exist. We could fix that by parsing CPP in configure (once) or in GHC (at every invocation) or stick with your original design (which I did for now in my branch).
perhaps it'd be better to have distinct CPP programs for C and Haskell in the build model? I think, yes.
I don't fully understand what {{{--with-gcc}}} is supposed to do. It changes the C compiler half way through configure and then even sets {{{CC}}}. The wiki says it specified the compiler used to compile C files but GHC will use its own C compiler. To me that sounds like we should actually set the C compiler using {{{CC=<C compiler>}}} on the configure command line. But I might be missing a major issue here.
Does this mean they should be disjoint in GHC's dynflags too? Do you mean there should be another set of CPP and CPPFLAGS for C files? I don't think so.

(though you are pointing out a real bug i think too) 1) theres currently (and unfortunately), some places in the build system where GCC is hard coded. a) historically the only C compiler GHC would support was GCC. thus historically --with-gcc was just a way of picking which gcc to use system with more than one gcc installed (I think, i could be wrong here) b) the clang support for ghc is pretty recent, and theres definitely a few corners that still need cleanup the CPP mode for Haskell code is always "traditional mode", so the flags passed to haskell CPP != the flags passed to C, though there may be some overlap -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8683#comment:24 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

This seems work 2) allowing ghc to be built with different CC and CPP. this doesn't quite work, but it does allow use to set it explicitly, and initializes the right fields in settings, but theres CPP stuff lying all around the build system that i'm still unfamiliar with and haven't been address here. this also add --with-cpp and --with-cpp-flags flags to configure currently for building things, -with-cpp and with-gcc need to point to the same program or various bugs in the build system start creeping up! It also seems to have surfaced at least one new race condition in the build system. I will try to dig into that more later. What i also need to finally test properly is if the resulting ghc can handle its settings file being pointed to cpphs Also i thought i had added logic to handle cpphs as a cpp option, but it looks like i lost track of that commit -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8683#comment:32 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I don't think it will be common, but it's something to watch out for. Imagine this scenario: You're making an FFI binding and `clang` and `gcc` use different definitions in their respective libraries. Or stranger yet, someone has written their library to behave differently depending on whether it's compiled with `clang` or `gcc` (let's hope no one does that). Thinking about this lead to realizing that cabal + hsc2hs exhibits a related problem: https://github.com/haskell/cabal/issues/1858 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8683#comment:62 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Its imposible to correctly compile SIMD codes with xcode 4s GCC 4.2, so i've had to have custom SETUP.hs files for OS X code that invokes clang on c codes, even if ghc is using gcc for its own needs. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8683#comment:63 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

This enables the Mac build to have a single build, which can be re-configured for the target machine after it has been copied onto the target machine. This is important as otherwise the HP would have to be distributed either in two forms (one for clang, one for non-clang), or with the ghc-clang- wrapper hack, which works but is brittle. Assuming this goes in, the next HP will have a script, activate-hs, which will allow the user to switch between installactions of the HP, and will also fix up these settings in cases where the users tool chain has switched from non-clang to clang. (This can happen on systems where the user has been using an old Xcode and then updates Xcode.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8683#comment:67 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
