objc-hi/objcxx-hi should be skipped when cross compiling. The existing opsys('darwin') predicate only asserts the host system is darwin but tells us nothing about the target, hence the oversight. -
Since 6755d833 this code is dead.

- Change arguments order to avoid `\args -> ...` lambdas - Fix documentation - Rename StgToCmm options ("big" doesn't mean anything)

Leftover from !9229.
-
Fixes #24899. Also place it under `extra-doc-files` to better reflect its nature and avoid triggering unnecessary recompilation if it changes.

This commit mentions removal of 32-bit darwin/ios support (#24921) in the 9.12 changelog.
-
This commit removes 32-bit darwin logic from the testsuite given it's no longer supported (#24921). Also contains more cleanup of obsolete i386 windows logic.
-
This commit removes 32-bit darwin/ios targets from llvm-targets given we no longer support them (#24921).
-
This commit removes 32-bit darwin/ios related logic from the rts, given we no longer support them (#24921).
-
This commit removes all 32-bit darwin logic from the compiler, given we no longer support 32-bit apple systems (#24921). Also contains a bit more cleanup of obsolete i386 windows logic.
-
This commit removes mentioning of OSDarwin from speedHack, since speedHack is purely for i386 and we no longer support i386 darwin (#24921).
-
This commit applies path normalization via cygpath -m to some build-time dependencies on Windows. Without this logic, the /clang64/bin prefixed msys2-style paths cause the build to fail with --enable-distro-toolchain.

-
This commit removes unused PowerPC/IA64 native adjustor code which is never actually enabled by autoconf/hadrian. Fixes #24920.
-
This patch removes CompilerInfo/LinkerInfo types from the compiler since they aren't actually used anywhere.
-
This function should never be inlined in order to keep code size small.

This commit enables +text_simdutf flavour transformer for wasm jobs, so text is now built with simdutf support for wasm.
-
This patch adds a +text_simdutf flavour transformer to hadrian to allow downstream packagers and users that build from source to opt-in simdutf support for text, in order to benefit from SIMD speedup at run-time. It's still disabled by default for the time being.
-
Adds support for emitting the clz and rbit instructions, which are used by GHC.Prim.clz*#, GHC.Prim.ctz*# and GHC.Prim.bitReverse*#.
-
This patch adds minor improvements to hadrian user settings documentation: - Add missing `ghc.cpp.opts` case - Remove non-existent `cxx` case - Clarify `cc.c.opts` also works for C++, while `cc.deps.opts` doesn't - Add example of passing configure argument to autoconf packages
-
This commit mentions removal of i386 Windows support and stdcall related change in the 9.12 changelog.
-
This commit include minor adjustments of documentation related to stdcall removal.
-
This patch adjusts test cases to handle the stdcall removal: - Some stdcall usages are replaced with ccall since stdcall doesn't make sense anymore. - We also preserve some stdcall usages, and check in the expected warning messages to ensure GHC always warn about stdcall usages (-Wunsupported-calling-conventions) as expected. - Error code testsuite coverage is slightly improved, -Wunsupported-calling-conventions is now tested. - Obsolete code paths related to i386 windows are also removed.
-
This commit removes stdcall related legacy logic in libraries and utils. ccall should be used uniformly for all supported windows hosts from now on.
-
This commit removes i386 windows from llvm-targets and the script to generate it.
-
This commit removes legacy i386 windows logic in autoconf scripts.
-
This commit removes some legacy i386 windows related code paths in the RTS, given this target is no longer supported.
-
We have formally dropped i386 windows support (#18487) a long time ago. The stdcall foreign call convention is only used by i386 windows, and the legacy logic around it is a significant maintenance burden for future work that adds arm64 windows support (#24603). Therefore, this patch removes stdcall support completely from the compiler as well as the RTS (#24883): - stdcall is still recognized as a FFI calling convention in Haskell syntax. GHC will now unconditionally emit a warning (-Wunsupported-calling-conventions) and treat it as ccall. - Apart from minimum logic to support the parsing and warning logic, all other code paths related to stdcall has been completely stripped from the compiler. - ghci only supports FFI_DEFAULT_ABI and ccall convention from now on. - FFI foreign export adjustor code on all platforms no longer handles the stdcall case and only handles ccall from now on. - The Win32 specific parts of RTS no longer has special code paths for stdcall. This commit is the final nail on the coffin for i386 windows support. Further commits will perform more housecleaning to strip the legacy code paths and pave way for future arm64 windows support.

This commit introduces a new language extension, `-XOrPatterns`, as described in GHC Proposal 522. An or-pattern `pat1; ...; patk` succeeds iff one of the patterns `pat1`, ..., `patk` succeed, in this order. See also the summary `Note [Implmentation of OrPatterns]`.

This commit fixes a subtle mistake in alignmentFromTypes that used to generate Unaligned when element type & index type are the same width. Fixes #24930.
-
For each module in a GHCi session, we keep alive one `ModLocation`. A `ModLocation` is fairly inefficiently packed, as `String`s are expensive in memory usage. While benchmarking the agda codebase, we concluded that we keep alive around 11MB of `FilePath`'s, solely retained by `ModLocation`. We provide a more densely packed encoding of `ModLocation`, by moving from `FilePath` to `OsPath`. Further, we migrate the full `Finder` component to `OsPath` to avoid unnecessary transformations. As the `Finder` component is well-encapsulated, this requires only a minimal amount of changes in other modules. We introduce pattern synonym for 'ModLocation' which maintains backwards compatibility and avoids breaking consumers of 'ModLocation'.

Implements the algorithm from compiler-rt's udiv128by64to64default. This rewrite results in a roughly 24x improvement in runtime on AArch64 (and likely any other arch that uses it).
