This patch removes the TCvSubst data type and instead uses Subst as
the environment for both term and type level substitution. This
change is partially motivated by the existential type proposal,
which will introduce types that contain expressions and therefore
forces us to carry around an "IdSubstEnv" even when substituting for
types. It also reduces the amount of code because "Subst" and
"TCvSubst" share a lot of common operations. There isn't any
noticeable impact on performance (geo. mean for ghc/alloc is around
0.0% but we have -94 loc and one less data type to worry abount).
Currently, the "TCvSubst" data type for substitution on types is
identical to the "Subst" data type except the former doesn't store
"IdSubstEnv". Using "Subst" for type-level substitution means there
will be a redundant field stored in the data type. However, in cases
where the substitution starts from the expression, using "Subst" for
type-level substitution saves us from having to project "Subst" into a
"TCvSubst". This probably explains why the allocation is mostly even
despite the redundant field.
The patch deletes "TCvSubst" and moves "Subst" and its relevant
functions from "GHC.Core.Subst" into "GHC.Core.TyCo.Subst".
Substitution on expressions is still defined in "GHC.Core.Subst" so we
don't have to expose the definition of "Expr" in the hs-boot file that
"GHC.Core.TyCo.Subst" must import to refer to "IdSubstEnv" (whose
codomain is "CoreExpr"). Most functions named fooTCvSubst are renamed
into fooSubst with a few exceptions (e.g. "isEmptyTCvSubst" is a
distinct function from "isEmptySubst"; the former ignores the
emptiness of "IdSubstEnv"). These exceptions mainly exist for
performance reasons and will go away when "Expr" and "Type" are
mutually recursively defined (we won't be able to take those
shortcuts if we can't make the assumption that expressions don't
appear in types).

This patch fixes quite a tricky leak where we would end up retaining
stale ModDetails due to rehydrating modules against non-finalised
interfaces.
== Loops with multiple boot files
It is possible for a module graph to have a loop (SCC, when ignoring boot files)
which requires multiple boot files to break. In this case we must perform the
necessary hydration steps before and after compiling modules which have boot files
which are described above for corectness but also perform an additional hydration step
at the end of the SCC to remove space leaks.
Consider the following example:
┌───────┐ ┌───────┐
│ │ │ │
│ A │ │ B │
│ │ │ │
└─────┬─┘ └───┬───┘
│ │
┌────▼─────────▼──┐
│ │
│ C │
└────┬─────────┬──┘
│ │
┌────▼──┐ ┌───▼───┐
│ │ │ │
│ A-boot│ │ B-boot│
│ │ │ │
└───────┘ └───────┘
A, B and C live together in a SCC. Say we compile the modules in order
A-boot, B-boot, C, A, B then when we compile A we will perform the hydration steps
(because A has a boot file). Therefore C will be hydrated relative to A, and the
ModDetails for A will reference C/A. Then when B is compiled C will be rehydrated again,
and so B will reference C/A,B, its interface will be hydrated relative to both A and B.
Now there is a space leak because say C is a very big module, there are now two different copies of
ModDetails kept alive by modules A and B.
The way to avoid this space leak is to rehydrate an entire SCC together at the
end of compilation so that all the ModDetails point to interfaces for .hs files.
In this example, when we hydrate A, B and C together then both A and B will refer to
C/A,B.
See #21900 for some more discussion.
-------------------------------------------------------
In addition to this simple case, there is also the potential for a leak
during parallel upsweep which is also fixed by this patch. Transcibed is
Note [ModuleNameSet, efficiency and space leaks]
Note [ModuleNameSet, efficiency and space leaks]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
During unsweep the results of compiling modules are placed into a MVar, to find
the environment the module needs to compile itself in the MVar is consulted and
the HomeUnitGraph is set accordingly. The reason we do this is that precisely tracking
module dependencies and recreating the HUG from scratch each time is very expensive.
In serial mode (-j1), this all works out fine because a module can only be compiled after
its dependencies have finished compiling and not interleaved with compiling module loops.
Therefore when we create the finalised or no loop interfaces, the HUG only contains
finalised interfaces.
In parallel mode, we have to be more careful because the HUG variable can contain
non-finalised interfaces which have been started by another thread. In order to avoid
a space leak where a finalised interface is compiled against a HPT which contains a
non-finalised interface we have to restrict the HUG to only the visible modules.
The visible modules is recording in the ModuleNameSet, this is propagated upwards
whilst compiling and explains which transitive modules are visible from a certain point.
This set is then used to restrict the HUG before the module is compiled to only
the visible modules and thus avoiding this tricky space leak.
Efficiency of the ModuleNameSet is of utmost importance because a union occurs for
each edge in the module graph. Therefore the set is represented directly as an IntSet
which provides suitable performance, even using a UniqSet (which is backed by an IntMap) is
too slow. The crucial test of performance here is the time taken to a do a no-op build in --make mode.
See test "jspace" for an example which used to trigger this problem.

I realised hydration was completely irrelavant for this cache because
the ModDetails are pruned from the result. So now it simplifies things a
lot to just store the ModIface and Linkable, which we can put into the
cache straight away rather than wait for the final version of a
HomeModInfo to appear.

The former behaviour of adding cost centres after optimization but
before unfoldings are created is not available via the flag
`prof-late-inline` instead.
I also reduced the overhead of -fprof-late* by pushing the cost centres
into lambdas. This means the cost centres will only account for
execution of functions and not their partial application.
Further I made LATE_CC cost centres it's own CC flavour so they now
won't clash with user defined ones if a user uses the same string for
a custom scc.
LateCC: Don't put cost centres inside constructor workers.
With -fprof-late they are rarely useful as the worker is usually
inlined. Even if the worker is not inlined or we use -fprof-late-linline
they are generally not helpful but bloat compile and run time
significantly. So we just don't add sccs inside constructor workers.

Previously we would attempt to test hadrian bootstrapping in the
`validate` build flavour. However, `ci.sh` refuses to run validation
builds during release pipelines, resulting in job failures. Fix this by
testing bootstrapping in the `release` flavour during release pipelines.
We also attempted to record perf notes for these builds, which is
redundant work and undesirable now since we no longer build in a
consistent flavour.

In #19143 I noticed that newArray# failed to initialize the card table
of newly-allocated arrays. However, embarrassingly, I then only fixed
the issue in newArrayArray# and, in so doing, introduced the potential
for an integer underflow on zero-length arrays (#21962).
Here I fix the issue in newArray#, this time ensuring that we do not
underflow in pathological cases.
Fixes #19143.

In general we want to ensure that the tested environment is as similar

this means we want to use the system's BSD command-line utilities, not
coreutils.

It turns out that `cp -P` on Darwin does not always copy a symlink as
a symlink. In order to get these semantics one must pass `-RP`. It's not
entirely clear whether this is valid under POSIX, but it is nevertheless
what Apple does.

Previously hadrian's bindist Makefile would modify package

However, the use of `mv` means that if umask is set then the user may
otherwise end up with package registrations which are inaccessible.
Fix this by ensuring that the mode is 0644.

Fix for #21651
Fixes three bugs:
- writes to eventManager should be atomic. It is accessed concurrently by ioManagerCapabilitiesChanged and closeFdWith.
- The race in closeFdWith described in the ticket.
- A race in getSystemEventManager where it accesses the 'IOArray' in
'eventManager' before 'ioManagerCapabilitiesChanged' has written to
'eventManager', causing an Array Index exception. The fix here is to
'yield' and retry.

This patch adds a new command-line flag:
-fplugin-library=<file-path>;<unit-id>;<module>;<args>
used like this:
-fplugin-library=path/to/plugin.so;package-123;Plugin.Module;["Argument","List"]
It allows a plugin to be loaded directly from a shared library. With
this approach, GHC doesn't compile anything for the plugin and doesn't
load any .hi file for the plugin and its dependencies. As such GHC
doesn't need to support two environments (one for plugins, one for
target code), which was the more ambitious approach tracked in #14335.

Previously we would attempt to install documentation even if the `doc`
directory doesn't exist (e.g. due to `--docs=none`). This would result
in the surprising side-effect of the entire contents of the bindist
being installed in the destination documentation directory. Fix this.
Fixes #21976.

Apple's ABI documentation [1] says: "The platforms reserve register x18.
Don’t use this register." While this wasn't problematic in previous
Darwin releases, macOS 13 appears to start zeroing this register
periodically. See #21964.

For the code
{-# LANGUAGE OverloadedRecordUpdate #-}
operatorUpdate f = f{(+) = 1}
There are no exact print annotations for the parens around the +

This MR fixes that.
