Change #23715 changed the localloc stack probe loop to load a
negative constant instead of zero to start the probing loop.
This increased the size of the probing loop, and hence the
size of the maximum prolog, by 4 bytes. Bump the assert on
the maximum size to match.
Note that as the comment says, the maximum size there is not
actually a maximum (it was originally), it is just to alert
us when the maximum generated prolog size has gone up.
Fixes #23920

nits on Windows (#20730)
* Remove implicit c-string const casting and clean up some C++ standards conformance bugs.
* Fix const string conversion in FCSigCheck.

To optimize code size we only added a UWC_END code if the last code in
uecMem does not equal UWC_END. However, the uec codes are variable sized
and allow any value to follow the code. Therefore, the value has the
small possibility to equal the value of UWC_END (0x4e on arm64
and 0xFF on arm32). Which incorrectly leaves the unwind array
unterminated.

This change is the result of running clang-tidy and clang-format on jit
sources.
|
|
This change starts the process of updating the jit code to make it ready
for being formatted by clang-format. Changes mostly include reflowing
comments that go past our column limit and moving comments around ifdefs
so clang-format does not modify the indentation. Additionally, some
header files are manually reformatted for pointer alignment and marked
as clang-format off so that we do not lose the current formatting.

Basically this enable function fragment.
Unwind data for arm64 can express only 1MB range.
For the large function, we should split unwind data for each fragment of
function. Other than the first fragment (the host region), each fragment
has a phantom prolog starting with "end_c(0xe5)".
I confirmed that this implementation aligns with window's unwinder, and
tested with COMPlus_JitSplitFunctionSize=32 for a few test cases which
split both main and funclets.

c_runtime/vprintf/test1 is disabled as casting NULL to va_list is
against the C specification.
Fix SetFilePointer tests on 32 bit platforms.
Define _FILE_OFFSET_BITS=64 so that we have long file support on 32 bit
platforms.
Implement context capture/restore for ARM.
Link libgcc_s before libunwind on ARM so C++ exceptions work.
Translate armasm to gas syntax.
Specify Thumb, VFPv3, ARMv7 for the ARM target.
Add ARM configuration to mscorlib build
Implement GetLogicalProcessorCacheSizeFromOS in PAL.
Set UNWIND_CONTEXT_IS_UCONTEXT_T from configure check.
