A future C-- test called T24474-cmm-override-g0 relies on the GCC-specific behaviour of -g3 implying -dD, which, in turn, leads to it emitting #defines past the preprocessing stage. Clang, at least, does not do this, so the test would fail if ran on Clang. As the behaviour here being tested is ``-optCmmP-g3'' undoing effects of the workaround we apply as a fix for bug #24474, and the workaround was for GCC-specific behaviour, the test needs to be marked as fragile on other compilers.

This patch includes all wasm32-specific testsuite fixes.
-
This patch adds the req_process predicate to the testsuite to assert the platform has a process model, also marking tests that involve spawning processes as req_process. Also bumps hpc & process submodule.
-
This patch adds the req_ghc_with_threaded_rts predicate to the testsuite to assert the platform has threaded RTS, and mark some tests as req_ghc_with_threaded_rts. Also makes ghc_with_threaded_rts a config field instead of a global variable.

Despite Cabal supporting any architecture name, `cabal --check` only supports a few built-in ones. Sadly `cabal --check` is used by Hackage hence using any non built-in name in a package (e.g. `arch(js)`) is rejected and the package is prevented from being uploaded on Hackage. Luckily built-in support for the `javascript` architecture was added for GHCJS a while ago. In order to allow newer `base` to be uploaded on Hackage we make the switch from `js` to `javascript` architecture. Fixes #22740. Co-authored-by:Ben Gamari <ben@smart-cactus.org>

See #22630 and !9552 This commit: - splits req_smp into req_target_smp and req_ghc_smp - changes the testsuite driver to calculate req_ghc_smp - changes a handful of tests to use req_target_smp instead of req_smp - changes a handful of tests to use req_host_smp when needed The problem: - the problem this solves is the ambiguity surrounding req_smp - on master req_smp was used to express the constraint that the program being compiled supports smp _and_ that the host RTS (i.e., the RTS used to compile the program) supported smp. Normally that is fine, but in cross compilation this is not always the case as was discovered in #22630. The solution: - Differentiate the two constraints: - use req_target_smp to say the RTS the compiled program is linked with (and the platform) supports smp - use req_host_smp to say the RTS the host is linked with supports smp WIP: fix req_smp (target vs ghc) add flag to separate bootstrapper split req_smp -> req_target_smp and req_ghc_smp update tests smp flags cleanup and add some docstrings only set ghc_with_smp to bootstrapper on S1 or CC Only set ghc_with_smp to bootstrapperWithSMP of when testing stage 1 and cross compiling test the RTS in config/ghc not hadrian re-add ghc_with_smp fix and align req names fix T11760 to use req_host_smp test the rts directly, avoid python 3.5 limitation test the compiler in a try block align out of tree and in tree withSMP flags mark failing tests as host req smp testsuite: req_host_smp --> req_ghc_smp Fix ghc vs host, fix ghc_with_smp leftover

Previously the output from test compilations used to determine whether, e.g., profiling libraries are available was shown with verbosity levels >= 2. However, the default level is 2, meaning that most users were often spammed with confusing errors. Fix this by bumping the verbosity threshold for this output to >=3. Fixes #21760.

Here we deprecate the eventlogging RTS ways and instead enable eventlog support in the remaining ways. This simplifies packaging and reduces GHC compilation times (as we can eliminate two whole compilations of the RTS) while simplifying the end-user story. The trade-off is a small increase in binary sizes in the case that the user does not want eventlogging support, but we think that this is a fine trade-off. This also revealed a latent RTS bug: some files which included `Cmm.h` also assumed that it defined various macros which were in fact defined by `Config.h`, which `Cmm.h` did not include. Fixing this in turn revealed that `StgMiscClosures.cmm` failed to import various spinlock statistics counters, as evidenced by the failed unregisterised build. Closes #18948.

Previously `test.mk` would try to determine whether the dynamic, profiling, and vanilla library ways are available by searching for `PrimOpWrappers.{,dyn_,p_}hi` in directory reported by `ghc-pkg field ghc-prim library-dirs`. However, this is extremely fragile as there is no guarantee that there is only one library directory. To handle the case of multiple `library-dirs` correct we would have to carry out the delicate task of tokenising the directory list (in shell, no less). Since this isn't a task that I am eager to solve, I have rather moved the detection logic into the testsuite driver and instead perform a test compilation in each of the ways. This should be more robust than the previous approach. I stumbled upon this while fixing #20579.

The main motivation for this patch is to allow tests to be added to the testsuite which test things about the source tree without needing to build GHC. In particular the notes linter can easily start failing and by integrating it into the testsuite the process of observing these changes is caught by normal validation procedures rather than having to run the linter specially. With this patch I can run ``` ./hadrian/build test --flavour=devel2 --only="uniques" ``` In a clean tree to run the checkUniques linter without having to build GHC. Fixes #21029

Using ghc_plugin_way had the unintended effect of meaning certain tests weren't run at all when ghc_dynamic=true, if you delete this modifier then the tests work in both the static and dynamic cases.

Previously it was unclear whether req_shared_libs should require: * that the platform supports dynamic library loading, * that GHC supports dynamic linking of Haskell code, or * that the dyn way libraries were built Clarify by splitting the predicate into two: * `req_dynamic_lib_support` demands that the platform support dynamic linking * `req_dynamic_hs` demands that the GHC support dynamic linking of Haskell code on the target platform Naturally `req_dynamic_hs` cannot be true unless `req_dynamic_lib_support` is also true.

Using a hash map reduces the complexity of lookupIPE(), making it non linear. On registration each IPE list is added to a temporary IPE lists buffer, reducing registration time. The hash map is built lazily on first lookup. IPE event output to stderr is added with tests. For details, please see Note [The Info Table Provenance Entry (IPE) Map]. A performance test for IPE registration and lookup can be found here: !5724 (comment 370806)

Dynamic-by-default was a mechanism to automatically select the -dynamic way for some targets. It was implemented in a convoluted way: it was defined as a flavour option, hence it couldn't be passed as a global settings (which are produced by `configure` before considering flavours), so a build system rule was used to pass -DDYNAMIC_BY_DEFAULT to the C compiler so that deriveConstants could infer it. * Make build system has it disabled for 8 years (951e28c0) * It has never been implemented in Hadrian * Last time someone tried to enable it 1 year ago it didn't work (!2436) * Having this as a global constant impedes making GHC multi-target (see !5427) This commit fully removes support for dynamic-by-default. If someone wants to reimplement something like this, it would probably need to move the logic in the compiler. (Doing this would probably need some refactoring of the way the compiler handles DynFlags: DynFlags are used to store and to pass enabled ways to many parts of the compiler. It can be set by command-line flags, GHC API, global settings. In multi-target GHC, we will use DynFlags to load the target platform and its constants: but at this point with the current DynFlags implementation we can't easily update the existing DynFlags with target-specific options such as dynamic-by-default without overriding ways previously set by the user.)

As noted in #18560, we previously would always run the LLVM ways since `configure` would set `SettingsLlcCommand` to something non-null when it otherwise couldn't find the `llc` executable. Now we rather probe for the existence of the `llc` executable in the testsuite driver. Fixes #18560.

Fixes #17937 Previously compacting GC simply ignored CNFs. This is mostly fine as most (see "What about small compacts?" below) CNF objects don't have outgoing pointers, and are "large" (allocated in large blocks) and large objects are not moved or compacted. However if we do GC *during* sharing-preserving compaction then the CNF will have a hash table mapping objects that have been moved to the CNF to their location in the CNF, to be able to preserve sharing. This case is handled in the copying collector, in `scavenge_compact`, where we evacuate hash table entries and then rehash the table. Compacting GC ignored this case. We now visit CNFs in all generations when threading pointers to the compacted heap and thread hash table keys. A visited CNF is added to the list `nfdata_chain`. After compaction is done, we re-visit the CNFs in that list and rehash the tables. The overhead is minimal: the list is static in `Compact.c`, and link field is added to `StgCompactNFData` closure. Programs that don't use CNFs should not be affected. To test this CNF tests are now also run in a new way 'compacting_gc', which just passes `-c` to the RTS, enabling compacting GC for the oldest generation. Before this patch the result would be: Unexpected failures: compact_gc.run compact_gc [bad exit code (139)] (compacting_gc) compact_huge_array.run compact_huge_array [bad exit code (1)] (compacting_gc) With this patch all tests pass. I can also pass `-c -DS` without any failures. What about small compacts? Small CNFs are still not handled by the compacting GC. However so far I'm unable to write a test that triggers a runtime panic ("update_fwd: unknown/strange object") by allocating a small CNF in a compated heap. It's possible that I'm missing something and it's not possible to have a small CNF.

Previously it would hackily look at the flavour name to determine whether LLVM was used to build stage2 ghc. However, this didn't work at all with Hadrian and would miss cases like ARM where we use the LLVM backend by default. See #16087 for the motivation for why ghc_built_by_llvm is needed at all. This should catch one of the ARMv7 failures described in #17555.

The option `confdir` (used in GhostScript test) was set correctly via `--config` in `test.mk` and incorrectly via `config/ghc`. AFAICT, some time ago this was working because the incorrect assignment was done first, and later it broke. Hardian doesn't pass `confdir`. I removed `confdir` and use `config.top` to determine the directory of the `good.ps` and `bad.ps` files. This is simpler. I also removed some redundant assignments in `config/ghc`.
