e79e4277 ("[ fix ] Make Bits types use int switch statement in RefC")
made the RefC backend generate code calling `extractInt` with Bits
types, bit did not add the extra cases to `extractInt`. This commit adds
the missing cases.
Fixes#2452
Modern compilers should be smart enough regardless and generate
efficient code for the sequence of ifs, this is really just a syntax
change to make the code shorter.
* RefC backend improvements
1. OnCollect had the wrong number of arguments. The code creator expects
3 arguments, but onCollect in prim.h expected 4 arguments. The first of which
was an erased arguments. That is now fixed.
2. OnCollect did not call `newReference` when creating a new reference to the pointer
and the freeing function
3. OnCollect and OnCollectAny still had a spurious printf statement
Those issues have been fixed, the test case can be found in
tests/refc/garbageCollect
4. The IORef mechanism expects that the %World token will be passed around
consistently. This is not the case. States in Control.App make use of
IORefs, but the function created from Control.App.prim_app_bind
had the world token erased to NULL.
Now, IORefs are managed using a global variable,
IORef_Storage * global_IORef_Storage;
referenced in cBackend.h, defined in the created .c file, and set to NULL
in main();
5. While multithreading and forking is still not supported, compiling a program
that makes use of Control.App demands a C implementation of prim_fork.
Files support/refc/threads.c and support/refc/threads.h provide a
dummy implementation for it, so that Control.App programs compile and run.
A test for these 2 issues is given in tests/refc/issue2424

Previously, the RefC files were located in IDRIS2_PREFIX. This is
decoupled to allow users to change the prefix (for ad-hoc library
install locations, for example).
To be able to use `C` functions for both Scheme and RefC: it was
not possible for `Buffer` before this PR.
As an example, `writeBufferData` and `readBufferData` functions are
removed: generic C backend implementations are used instead.
Pragma once is supported by all compilers for the last ten years.
Better use it instead of include guards (which use different styles
in different files).
The cast to float needs to happen before the division, otherwise integer
division will be performed, and as a result `CLOCKS_PER_NSEC` will
always be 0 if `CLOCKS_PER_SEC` < `NSEC_PER_SEC`.
* Add utility functions to treat All as a heterogeneous container
* Distinguish RefC Int and Bits types
* Change RefC Integers to be arbitrary precision
* Add RefC Bits maths operations
* Make RefC div and mod Euclidean
* Add RefC bit-ops tests
* Add RefC integer comparison tests
* Add RefC IntN support
The external type must be a Value object for garbage collection reasons.
For completely custom types, use a GCPointer, with appropriate GC function for clearing up your data type.

Written by Volkmar Frinken (@vfrinken). This is intended as a
lightweight (i.e. minimal dependencies) code generator that can be
ported to multiple platforms, especially those with memory constraints.
It shouldn't be expected to be anywhere near as fast as the Scheme back
end, for lots of reasons. The main goal is portability.
