This was done because originally getting the finalized asmlist happend
through a single proc that either called the vectorized version or the
regular version depending on the presence of tcalo_vectorized_* flags.
Nowadays, calling either get_final_asmlist_vectorized_dead_strip or
get_final_asmlist happens directly as needed.
This flag will be used by the LLVM asmwriter to add appropriate
address sanitizer information.
When the RTL is built for Mac OS X 10.6 or newer, use the new versions
and the corresponding alternate system library functions.
Also extracted the Darwin stat record definition to reduce the
ifdef hell.
- Stack pointer is kept below register save area. This ensures that
registers are not overwritten by interrupt handlers.
- RV32 and 64 code is merged to base class.
These changes adds an additional record field to record structure TMsgPort in
order to support SMP for ABIv11 (non m68k targets only).
This additional field contains two opaque IPTR's/PtrUInt's and therefor breaks
compatibility between ABIv0, ABIv1 and ABIv11 as well as make them binary
incompatible.
It also renders ABIv11 incompatible with itself when this change was introduced
on march 18 2022. Recompilation of existing code for this ABI is thus required.
See: b9bc67accc
These changes makes sure that the use of record structure spinlock is not
active/available when compiling for AROS ABIv11 as that ABI does not support
spinlocks as implemented for AROS ABIv1.
Note that this is a ABI and Binary Compatible break between ABIv1 and ABIv11.
These changes makes sure that the use of record structure TSpinlock can only
be enabled/active for AROS ABIv1 as that ABI is currently the only ABI that
is able to support SMP by using the spinlock record structure.
This commit will add an additional spinlock field to record structures
TMsgPort and TSemaphoreRequest for a SMP enabled build.
This will break ABI and Binary Compatibility between ABIv0 and ABIv1 and for
ABIv1 (for a SMP enabled build).
Recompilation in such case is required as both record structures TMsgPort and
TSemaphoreRequest are embedded in other record structures which causes a
myriad of changes to those records including different record sizes and other
field offsets.
Note that SMP is currently only available for ABIv1 and afaik only supported
for AROS target x86_64 while AROS target i386 has initial support for SMP
(but not actively enabled).
SMP enabled build can be 'activated' by defining AROS_PLATFORM_SMP and
AROSEXEC_SMP.
In 2015 ABIv1 introduced support for spinlocks for SMP enabled builds (1) by
use of a special spinlock structure.
This structure was later updated to end up in its current form in 2017 (2)
This commit adds this record structure to both RTL (execd) and unit (exec).
The structure can be "enabled" by defining AROSPLATFORM_SMP during build.
