In the bindist configure script we must rediscover the `otool` and `install_name_tool`s since they may be different from the build environment. Fixes #24211.

In XCode 15's linker, -single_module is the default and otherwise passing it as a flag results in a warning being raised: ld: warning: -single_module is obsolete This patch fixes this warning by, at configure time, determining whether the linker supports -single_module (which is likely false for all non-darwin linkers, and true for darwin linkers in previous versions of macOS), and using that information at runtime to decide to pass or not the flag in the invocation. Fixes #24168 -
Fixes #24167 XCode 15 introduced a new linker which warns on duplicate libraries being linked. To disable this warning, we pass -Wl,-no_warn_duplicate_libraries as suggested by Brad King in CMake issue #25297. This flag isn't necessarily available to other linkers on darwin, so we must only configure it into the CC linker arguments if valid.

For some reason there was an indirection via the Windres variable before setting WindresCmd. That indirection led to #23855. I then also noticed that these other variables were just not used anywhere when trying to work out what the correct condition was for this bit of the configure script.

This includes quite a lot of small fixes which fix the installation makefile to work on windows properly. This also required fixing the RelocatableBuild variable which seemed to have been broken for a long while. Sam helped me a lot writing this patch by providing a windows machine to test the changes. Without him it would have taken ages to tweak everything. Co-authored-by:sheaf <sam.derbyshire@gmail.com>

The "format" mode takes an "--input" and "--ouput" target file and formats it. This is intended to be useful on windows where the configure/ghc-toolchain target files can't be diffed very easily because the path separators are different.

The JavaScript code in libraries/base/jsbits/base.js had some hardcoded offsets for fields in structs, because we expected the layout of the data structures to remain unchanged. Emsdk 3.1.42 changed the layout of the stat struct, breaking this assumption, and causing code in .hsc files accessing the stat struct to fail. This patch improves compatibility with recent emsdk by removing the assumption that data layouts stay unchanged: 1. offsets of fields in structs used by JavaScript code are now computed by the configure script, so both the .js and .hsc files will automatically use the new layout if anything changes. 2. the distrib/configure script checks that the emsdk version on a user's system is the same version that a bindist was booted with, to avoid data layout inconsistencies See #23641

Add the ghc-toolchain binary to the binary distribution we ship to users, and teach the bindist configure to use the existing ghc-toolchain.

This commit integrates ghc-toolchain, the brand new way of configuring toolchains for GHC, with the Hadrian build system, with configure, and extends and improves the first iteration of ghc-toolchain. The general overview is * We introduce a program invoked `ghc-toolchain --triple=...` which, when run, produces a file with a `Target`. A `GHC.Toolchain.Target.Target` describes the properties of a target and the toolchain (executables and configured flags) to produce code for that target * Hadrian was modified to read Target files, and will both * Invoke the toolchain configured in the Target file as needed * Produce a `settings` file for GHC based on the Target file for that stage * `./configure` will invoke ghc-toolchain to generate target files, but it will also generate target files based on the flags configure itself configured (through `.in` files that are substituted) * By default, the Targets generated by configure are still (for now) the ones used by Hadrian * But we additionally validate the Target files generated by ghc-toolchain against the ones generated by configure, to get a head start on catching configuration bugs before we transition completely. * When we make that transition, we will want to drop a lot of the toolchain configuration logic from configure, but keep it otherwise. * For each compiler stage we should have 1 target file (up to a stage compiler we can't run in our machine) * We just have a HOST target file, which we use as the target for stage0 * And a TARGET target file, which we use for stage1 (and later stages, if not cross compiling) * Note there is no BUILD target file, because we only support cross compilation where BUILD=HOST * (for more details on cross-compilation see discussion on !9263) See also * Note [How we configure the bundled windows toolchain] * Note [ghc-toolchain consistency checking] * Note [ghc-toolchain overview] Ticket: #19877 MR: !9263

The previous configuration script to test whether Ld supported response files was * Incorrect (see #23542) * Used, in practice, to check if the *merge objects tool* supported response files. This commit modifies the macro to run the merge objects tool (rather than Ld), using a response file, and checking the result with $NM Fixes #23542

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 has no direct dependence on the linker. Rather, we depend upon the C compiler for linking and an object-merging program (which is typically `ld`) for production of GHCi objects and merging of C stubs into final object files. Despite this, for historical reasons we still recorded information about the linker into `settings`. Remove these entries from `settings`, `hadrian/cfg/system.config`, as well as the `configure` logic responsible for this information. Closes #23566.

When GHC invokes clang, it currently passes -Qunused-arguments to discard warnings resulting from GHC using multiple options that aren't used. In this commit, we configure -Qunused-arguments into the Cc options instead of checking if the compiler is clang at runtime and hardcoding the flag into GHC. This is part of the effort to centralise toolchain information in toolchain target files at configure time with the end goal of a runtime retargetable GHC. This also means we don't need to call getCompilerInfo ever, which improves performance considerably (see !10589).

These were previously hardcoded in configure (with no option for overriding them) and simply passed onto ghc through the settings file. Since configure already guarantees gcc supports those flags, we simply move them into GHC.

We move the "target has RTS linker" information out of configure into a predicate in GHC, and remove this option from the settings file where it is unnecessary -- it's information statically known from the platform. Note that previously we would consider `powerpc`s and `s390x`s other than `powerpc-ibm-aix*` and `s390x-ibm-linux` to have an RTS linker, but the RTS linker supports neither platform. Closes #23361

Previously we would use plain `cp` to install various parts of the binary distribution. However, `cp`'s behavior w.r.t. file attributes is quite unclear; for this reason it is much better to rather use `install`. Fixes #21965.

The motiviation for this flag is to be able to produce documentation which is suitable for uploading for hackage, ie, the cross-package links work correctly. There are basically three values you want to set this to: * off - default, base_url = ../%pkg% which works for local browsing * on - no argument , base_url = https:://hackage.haskell.org/package/%pkg%/docs - for hackage docs upload * on - argument, for example, base_url = http://localhost:8080/package/%pkg%/docs for testing the documentation. The `%pkg%` string is a template variable which is replaced with the package identifier for the relevant package. This is one step towards fixing #21749

We previously only checked the stage 1/2 compiler for --target support. We got away with this for quite a while but it eventually caught up with us in #21579, where `bytestring`'s new NEON implementation was unbuildable on Darwin due to Rosetta's seemingly random logic for determining which executable image to execute. This lead to a confusing failure to build `bytestring`'s cbits, when `clang` tried to compile NEON builtins while targetting x86-64. Fix this by checking CC_STAGE0 for --target support. Fixes #21579.

Here we introduce proper support for compilation of C++ objects. This includes: * logic in `configure` to detect the C++ toolchain and propagating this information into the `settings` file * logic in the driver to use the C++ toolchain when compiling C++ sources
