This will hopefully provide some indication whether MO_MulMayOflo is
excessively conservative.

This adds support for running pipelines from upstream jobs in ghc/ghc

Fix non-emulated case in simple

See merge request !15

The quotes are needed. Otherwise, the expression is always true.

Use an emulator (QEMU) to run "simple"

See merge request !13

This is useful for cross-platform development. Currently, the only
targeted emulator is QEMU.

Add hie.yaml to declare this as cabal project

See merge request !11

Fix CI pipeline issues

See merge request !12

Without this GHC flag calling convention tests fail with a panic.

The ghcup default cache may already exist on the runner machine, created
by an unrelated job. Configure a custom one to avoid conflicts.

Otherwise, Gitlab responds with HTTP 404 (not found.)

The hash is the same as used in current ghc pipelines.

Otherwise, hie-bios tries to find a stack executable.

Avoid mmap in static method

Closes #3

See merge request !8

Factor out default interpreter

Closes #3

See merge request !7

This introduces an abstraction over the static versus dynamic evaluation
method decision, allowing us to use the dynamic method where possible
and falling back to the static method where dynamic linking is not
supported (e.g. Webasm).

As it only applies to the dynamic evaluation method.

Add use of an emulator executable with the static evaluation method.

To allow easy usage of the static interpreter method.

Addresses #4.

Closes #3.

Consider a signed division such as (-128::W8) / (-1::W8). GHC lowers
this to IDIV which will throw an FP exception since the 8-bit target
register is too small to accommodate the result, 128.

Therefore, we are going to specify the Quot primop as being undefined
in cases where the result overflows.

See #1.
