Nikita Popov 29fa4d203a Don't mark non-refcounted phi as live 
If the value is not refcounted, then it doesn't matter if the
FREE gets dropped.

* PHP-7.4:
  Fix DCE of FREE of COALESCE
 2021-04-08 17:01:19 +02:00
Nikita Popov 0826a54836 Fix DCE of FREE of COALESCE 
When encountering the following SSA graph:

    BB1:
    #2.T1 [string] = COALESCE #1.CV0($str) [null, string] BB2

    BB2:
    #5.T1 [string] = QM_ASSIGN string("")

    BB3:
    #7.X1 [string] = Phi(#2.X1 [string], #5.X1 [string])
    FREE #7.T1 [string]

We would currently determine that #7, #5 are dead, and eliminate
the FREE and QM_ASSIGN. However, we cannot eliminate #2, as
COALESCE is also responsible for control flow.

Fix this my marking all non-CV phis as live to start with. This
can be relaxed to check the kind of the source instruction, but
I couldn't immediately come up with a case where it would be
useful.

Nikita Popov 82622d7583 Fix refcount inference for typed properties 
We were not adding RC1/RCN if the MAY_BE_OBJECT came from a class
type and there was no other refcounted type in the union.

Michael Heimpold eaf9421df6 ext/opcache: fix configure output while checking mmap MAP_ANON support 
It seems that f3efb9e3fb introduced a "typo" which may result
in the following confusing message:

checking for mmap() using MAP_ANON shared memory support... no=yes

Let's fix this.

Closes GH-6758.

Christoph M. Becker 1c16749eaa Merge branch 'PHP-7.4' into PHP-8.0 
* PHP-7.4:
  Print error code if CreateMutex() fails
 2021-03-05 15:08:24 +01:00
Christoph M. Becker e0e167e581 Print error code if CreateMutex() fails 
This issue came up recently in a bug report[1]; without the error code,
users can barely guess why the function failed.

[1] <https://bugs.php.net/80812>

Closes GH-6745.

 2021-02-04 17:07:30 +01:00
Nikita Popov 8b7aaad7d6 Try SIGTERM before SIGKILL in opcache restart 
SIGTERM is subject to HANDLE_BLOCK_INTERRUPTIONS(), which will
allow code to exit critical sections before it gets terminated.

Closes GH-6493.

Dylan K. Taylor 872f302b8d Keep JIT region executable under ZTS 
When one thread tries to compile a script, another thread may
already be executing JITed code. In this case we can't make the
memory non-executable.

This violates the W^X principle, but doesn't seem to be avoidable
for ZTS builds for now. The same problem does not exist for NTS,
as it's a different process executing there, which has it's own
memory protection mapping.

Closes GH-6595.

Dharman 44a311dbbe Fix/improve mysqli stubs 
* mysqli_commit $flags default value is 0, not -1.
* A number of functions cannot actually return null.
* mysqli_poll parameter names were incorrect, as this function
  has a different signature from select.
* fetch functions apart from fetch_all can return false on failure.
