* Don't consider tyAnd/tyNot/tyOr/tyAnything as generic
`containsGenericType` was too shallow and didn't check all the branches.
The resulting half-processed nodes are often simplified by the constant
folding pass but when that's not possible we get a nasty error during
codegen.
Fixes#8693
* Move the blame onto the semFold pass
Slightly better evaluation of `is` forms.
This is a temporary fix that will be reworked in a follow up commit
that aims to eliminate the tfExplicit flag from the compiler. The
complete and proper fix was considered too risky for inclusion just
before our 0.19 release.
* Goodbye postInitProc
* Give preInitProc its own scope
Avoid any conflict between the variables introduced by preInitProc and
initProc since both are codegen'd in the same function body.
* Fix codegen for global var init in emulated TLS
Fixes#8535
* Add test for #8535
* Keep a bogus stack frame around
* Remove more dead code
When a `var openArray[T]` function parameter goes trough the
`transformAddrDeref` pass we may lose the `var` specifier, leading to
nasty crashes at runtime.
* posix_other: Haiku now has spawn.h
This is added per https://dev.haiku-os.org/ticket/13446
* posix_other: Add Haiku specific Dirent members
* cpuinfo: Add an implementation for Haiku
* distros: Add basic Haiku support
* encodings: update Haiku support
* fenv, math: Haiku now provides libm
* times: Add Haiku struct members
* ansi_c, osalloc: Add Haiku constants
* threads: Add Haiku support
* testament: Haiku uses LIBRARY_PATH
* nim.cfg: Update Haiku support
libnetwork should only be linked if network functions are used
* threads: Haiku does not support -pthread switch
* tworkingdir: Haiku's env is in /bin
* posix_other: add SIGKILLTHR for Haiku
* sockets: link with libnetwork on Haiku
* coro: correct ucontext.h location
http://pubs.opengroup.org/onlinepubs/009696699/basedefs/ucontext.h.html
* coro: ucontext backend is not available on Haiku
Haiku doesn't provide the <ucontext.h> header, as it was removed from POSIX
* coro: fix setjmp backend
The compiler does not allow statements after a noreturn function
* nativesockets: Haiku doesn't support AI_V4MAPPED
* system: hostOS can contains "haiku"
* os: add support for Haiku's packagefs
packagefs is read-only, but there are writable holes to the underlying
file system as well
* os: update constant for Haiku
