      ghci: use plain malloc for mkConInfoTable on non-TNTC platforms · 1804f12f
      Cheng Shao authored 
      This patch avoids using mmap() to allocate executable memory for
mkConInfoTable on platforms without tables-next-to-code, see added
comment for explanation.

      rts: use page sized mblocks on wasm · 75956767
      Cheng Shao authored 
      This patch changes mblock size to page size on wasm. It allows us to
simplify our wasi-libc fork, makes it much easier to test third party
libc allocators like emmalloc/mimalloc, as well as experimenting with
threaded RTS in wasm.

      ghc-bignum: remove obsolete ln script · bb440214
      Cheng Shao authored 
      This commit removes an obsolete ln script in ghc-bignum/gmp. See
060251c2 for its original intention,
but it's been obsolete for a long time, especially since the removal
of the make build system. Hence the house cleaning.

      base: treat all FDs as "nonblocking" on wasm · a1a37769
      Cheng Shao authored 
      On posix platforms, when performing read/write on FDs, we check the
nonblocking flag first. For FDs without this flag (e.g. stdout), we
call fdReady() first, which in turn calls poll() to wait for I/O to be
available on that FD. This is problematic for wasm32-wasi: although
select()/poll() is supported via the poll_oneoff() wasi syscall, that
syscall is rather heavyweight and runtime behavior differs in
different wasi implementations. The issue is even worse when targeting
browsers, given there's no satisfactory way to implement async I/O as
a synchronous syscall, so existing JS polyfills for wasi often give up
and simply return ENOSYS.

Before we have a proper I/O manager that avoids poll_oneoff() for
async I/O on wasm, this patch improves the status quo a lot by merely
pretending all FDs are "nonblocking". Read/write on FDs will directly
invoke read()/write(), which are much more reliably handled in
existing wasi implementations, especially those in browsers.

Fixes #23275 and the following test cases: T7773 isEOF001 openFile009
T4808 cgrun025

      testsuite: req_smp --> req_target_smp, req_ghc_smp · 73528452
      Sylvain Henry authored and Cheng Shao's avatar Cheng Shao committed 
      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

      ghc-bignum: update gmp to 6.3.0 · af3e9b37
      Cheng Shao authored and Luite Stegeman's avatar Luite Stegeman committed 
      This patch bumps the gmp-tarballs submodule and updates gmp to 6.3.0.
The tarball format is now xz, and gmpsrc.patch has been patched into
the tarball so hadrian no longer needs to deal with patching logic
when building in-tree GMP.

      testsuite: Encoding test witnesses recent iconv bug is fragile · 3187fc76
      Rodrigo Mesquita authored and Zubin's avatar Zubin committed 
      A regression in the new iconv() distributed with XCode 15 and MacOS
Sonoma causes the test 'encoding004' to fail in the CP936 roundrip.

We mark this test as fragile until this is fixed upstream (rather than
broken, since previous versions of iconv pass the test)

See #24161

      Fix remaining issues with bound checking (#23123) · d86cd08b
      Sylvain Henry authored and Zubin's avatar Zubin committed 
      While fixing these I've also changed the way we store addresses into
ByteArray#. Addr# are composed of two parts: a JavaScript array and an
offset (32-bit number).

Suppose we want to store an Addr# in a ByteArray# foo at offset i.
Before this patch, we were storing both fields as a tuple in the "arr"
array field:

  foo.arr[i] = [addr_arr, addr_offset];

Now we only store the array part in the "arr" field and the offset
directly in the array:

  foo.dv.setInt32(i, addr_offset):
  foo.arr[i] = addr_arr;

It avoids wasting space for the tuple.
