- merge libcxxabi into libcxx for LLVM 12, 13, 14, 15, 16, 17, and git. - remove the link time workaround `-lc++ -lc++abi` from 58 packages as it is no longer required. - fixes https://github.com/NixOS/nixpkgs/issues/166205 - provides alternative fixes for. https://github.com/NixOS/nixpkgs/issues/269548 https://github.com/NixOS/nix/issues/9640 - pkgsCross.x86_64-freebsd builds work again This change can be represented in 3 stages 1. merge libcxxabi into libcxx -- files: pkgs/development/compilers/llvm/[12, git]/{libcxx, libcxxabi} 2. update stdenv to account for merge -- files: stdenv.{adapters, cc.wrapper, darwin} 3. remove all references to libcxxabi outside of llvm (about 58 packages modified) ### merging libcxxabi into libcxx - take the union of the libcxxabi and libcxx cmake flags - eliminate the libcxx-headers-only package - it was only needed to break libcxx <-> libcxxabi circular dependency - libcxx.cxxabi is removed. external cxxabi (freebsd) will symlink headers / libs into libcxx. - darwin will re-export the libcxxabi symbols into libcxx so linking `-lc++` is sufficient. - linux/freebsd `libc++.so` is a linker script `LINK(libc++.so.1, -lc++abi)` making `-lc++` sufficient. - libcxx/default.nix [12, 17] are identical except for patches and `LIBCXX_ADDITIONAL_LIBRARIES` (only used in 16+) - git/libcxx/defaul.nix does not link with -nostdlib when useLLVM is true so flag is removed. this is not much different than before as libcxxabi used -nostdlib where libcxx did not, so libc was linked in anyway. ### stdenv changes - darwin bootstrap, remove references to libcxxabi and cxxabi - cc-wrapper: remove c++ link workaround when libcxx.cxxabi doesn't exist (still exists for LLVM pre 12) - adapter: update overrideLibcxx to account for a pkgs.stdenv that only has libcxx ### 58 package updates - remove `NIX_LDFLAGS = "-l${stdenv.cc.libcxx.cxxabi.libName}` as no longer needed - swift, nodejs_v8 remove libcxxabi references in the clang override https://github.com/NixOS/nixpkgs/pull/292043

|
|
A fork of Open Watcom: A C/C++/Fortran compiler and assembler suite
|
|
targeting a multitude of architectures (x86, IA-32, Alpha AXP, MIPS,
|
|
PowerPC) and operating systems (DOS, OS/2, Windows, Linux).
|
|
|
|
Main differences from Open Watcom 1.9:
|
|
|
|
- New two-phase build system - Open Watcom can be built by the host's
|
|
native C/C++ compiler or by itself
|
|
- Code generator properly initializes pointers by DLL symbol addresses
|
|
- DOS tools now support long file names (LFN) if appropriate LFN driver
|
|
is loaded by DOS
|
|
- Open Watcom is ported to 64-bit hosts (Win64, Linux x64)
|
|
- Librarian supports x64 CPU object modules and libraries
|
|
- RDOS 32-bit C run-time compact memory model libraries are fixed
|
|
- Resource compiler and Resource editors support Win64 executables
|
|
- Open Watcom text editor is now self-contained, it can be used as
|
|
standalone tool without any requirements for any additional files or
|
|
configuration
|
|
- Broken C++ compiler pre-compiled header template support is fixed
|
|
- Many C++ compiler crashes are fixed
|
|
- Debugger has no length limit for any used environment variable
