* Require GHC 8.8 as the minimum compiler for bootstrappingRyan Scott2020-03-311-4/+0
| | | | | | | | This allows us to remove several bits of CPP that are either always true or no longer reachable. As an added bonus, we no longer need to worry about importing `Control.Monad.Fail.fail` qualified to avoid clashing with `Control.Monad.fail`, since the latter is now the same as the former.

* SysTools: Ensure that error parser can handle absolute paths on WindowsBen Gamari2020-03-101-3/+14
| | | | | | | This fixes #17786, where the error parser fails to correctly handle the drive name in absolute Windows paths. Unfortunately I couldn't find a satisfactory way to test this.

* SysTools: Use "process job" when spawning processes on WindowsTamar Christina2020-02-141-3/+16
| | | | | | | | | | | | | | GHC should make calls using process jobs when calling out to GCC and LD. The reason is these use the exec () family of posix functions. Window's process model doesn't allow replacement of processes so this is emulated by creating a new process and immediately exiting the old one. Because of this when using normal Windows wait functions you would return even without the child process having finished. In this case if you are depending on data from the child you will enter a race condition. The usual fix for this is to use process jobs and wait for the termination of all children that have ever been spawn by the process you called. But also waiting for the freeing of all resources.
* SysTools: Only apply Windows-specific workaround on WindowsBen Gamari2019-11-041-1/+7
| | | | | | | | | Issue #1110 was apparently due to a bug in Vista which prevented GCC from finding its binaries unless we explicitly added it to PATH. However, this workaround was incorrectly applied on non-Windows platforms as well, resulting in ill-formed PATHs (#17266). Fixes #17266.
* Update Trac ticket URLs to point to GitLabRyan Scott2019-03-151-1/+1
| | | | | This moves all URL references to Trac tickets to their corresponding GitLab counterparts.
* Split SysTools up someTamar Christina2017-10-101-0/+347
Summary: SysTools and DriverTools have an annoying mutual dependency. They also each contain pieces of the linker. In order for changes to be shared between the library and the exe linking code this dependency needs to be broken in order to avoid using hs-boot files.
