Previously we would generate function names for anonymous functions
on every AssignmentExpression, even if we weren't assigning a function.
We were also setting names of anonymous functions in arrays, which is
apparently a SpiderMonkey specific behavior not supported by V8, JSC
or required by ECMA262. This patch removes that behavior.
This is a huge performance improvement on the CanvasCycle demo! :^)
As a compromise, if the fimrware decided to set the IRQ line to be 7,
or something else we can't deal with, the user can simply force the code
to work with IRQ 11, with the boot argument "force_ahci_irq_11" being
set to "on".
Instead of polling if the device ended the operation, we can just use
interrupts for signalling about end of IO operation.
In similar way, we use interrupts during device detection.
Also, we use the new Work Queue mechanism introduced by @tomuta to allow
better performance and stability :)
We can't use deferred functions for anything that may require preemption,
such as copying from/to user or accessing the disk. For those purposes
we should use a work queue, which is essentially a kernel thread that
may be preempted or blocked.
This patch rethinks the way indexed property storage works:
Instead of having a cut-off point at 200 elements where we always move
to generic property storage, we now allow arrays to stay in simple mode
as long as we don't create a gap/hole larger than 200 elements.
We also simplify generic storage to only have a hash map (for now)
instead of juggling both a vector and a hash map. This is mostly fine
since the vast majority of arrays get to stay simple now.
This is a huge speedup on anything that uses basic JS arrays with more
than 200 elements in them. :^)
Otherwise we continuously lose the first sparse element (at index
SPARSE_ARRAY_THRESHOLD) without noticing, as we overwrite all indices
with the value at index+1.
Fixes#5884.
Alot of code is shared between i386/i686/x86 and x86_64
and a lot probably will be used for compatability modes.
So we start by moving the headers into one Directory.
We will probalby be able to move some cpp files aswell.
We previously ignored these values in the return value of
load_elf_object, which causes us to not allocate a TLS region for
statically-linked programs.
Previously, libc.a contained undefined symbols from ssp and libsystem,
which caused static compilation to fail.
We now generate libc.a with a custom CMake rule that combines all
object files from libc, ssp and libsystem to form libc.a
Closes#5758.
Build ELF executables with a zero length `GNU_STACK`
program header flagged non-executable.
The stack is never executable on SerenityOS regardless
of whether the `GNU_STACK` header is specified.
Specifically defining this header is more explicit,
as absence of this header implies an executable stack
on other systems (Linux).
