so it also works for 32 bit targets and a high level code generator
(where aint is still 32 bit, but 64 bit operations are not decomposed)
git-svn-id: trunk@41441 -
(cherry picked from commit 07bd4ba517)
With local change to fix compilation for x86_64 CPU
* x86_64: Fixed code generation for try..finally blocks, so that exit label from inner try..finally stays within scope of procedure's implicit try..finally block if one is present. Mantis #34772.
........
* patch by J. Gareth Moreton: propagate exit use in nested try...except statements,
resolves#35841
........
* fix#35841 also for break and continue

Integrate patch from bug report 35409.
Add possibiliy to throw InternalError
for unhandled case values inside tentryfile,
But avoid adding dependency on verbose unit
as this would break ppudump handling of ppu files.
Add RaiseAssertion virtual method to tentryfile class.
Call RaiseAssertion in tentryfile methods
where an internal error is wanted.
Override RaiseAssertion method in symtype.pas unit
to call InternalError.
Add new class tppudumpfile to override RaiseAssertion
in utils/ppuutils/ppudump.pp unit.

Fix recordtoken writing into ppu files to allow correct
handling in cross-configuration with different endianess.
The code has been modified to use the same scheme as the writing of
the other parts of the ppu, i.e. change_endian filed has been
added also to tscannerfile class of scanner unit.
This field is then used to swap values that required endianess
conversion.
* scanner.pas: change_endian filed added to tscannerfile class.
The value of this field is set as the same field in tentryfile class of entfile unit.
Token read and write methods converted to use change_endian field.
* ppu.pas: Increase CurrentPPILongVersion
* utils/ppuutils/ppudump.pp: Remove unneeded FPC_BIG_ENDIAN code
which was needed because tokens were previously written using a
different rule.

* Android: The list of supported syscalls has been auto-generated directly from android sources for each CPU.
* Minor adjustments to make all compilable with the proper list of Android syscalls.
........
* Re-generated lists of android syscalls by a new script. The lists are more correct now. The script's location: https://svn.freepascal.org/svn/fpcbuild/scripts/android
........
* Fixed UnhookSignal when RTL_SIGDEFAULT is passed. The bug have caused crash on aarch64-android due to out of bounds read of the rtlsig2ossig[] array.
........
+ Added support for the aarch64-android target.
........
* Set ICU data dir if it is not set by the system. It fixes issues on newer Android versions.
* Added more predefined ICU versions.
........
* android: Use the current dir as temp.
........
* Corrected TUContext record for aarch64-linux and aarch64-android. It fixes obtaining of an address of the instruction where a signal has thrown.
........
* Enabled safecall support for aarch64 to be on par with other cpus.
........
* Android: Reworked the startup code to use no assembly instructions. Generic assembler startup files contains only section data and are compiled for each CPU.
* Android: argc and argv are correct for shared libraries.
........
* Use syscall_nr_renameat for android.
........
+ added support for x86_64-android target.
........
+ Added the auto-generated list syscalls for mips64-android. It will be needed when mips64 is supported.
........
* x86_64-android requires sigreturn for proper signal handling.
........
* Register external gas assembler for aarch64-android and x86_64-android.
........
* Enabled compilation of the cpu unit for arm-android and x86_64-android.
........
* ucnv_open() must be called with some SSE exception masked on x86_64-android.
* Call u_init() during initialization.
........
* Create the ".note.gnu.build-id" section for android. It fixes debugging of shared libs in Android Studio.
........
* android: Removed cwstring from the uses clause of the unix unit. Use cwstring indirectly. It allows to avoid using cwstring if needed.
........
* ICU v3.8 on Android 1.5-2.1 is buggy and can't be unloaded properly.
........
* Fixed locale detection on new Android versions.
........
* Fixed obtaining a time zone information for 64-bit android.
........
* Since Android 8 the net.dnsX properties can't be read. Use Google Public DNS servers.
........
* android: Use libc for sockets since the "accept" syscall is blocked by SECCOMP, but the "accept4" alternative is not available on old Android versions (2.3 and older).
........
* android: Regenerated syscalls.
........
* android: Disabled usage of the "pselect6" and "ppoll" syscalls for arm-android. These syscalls are not available on old Android versions (2.3 or older).
........

tcpuparamanager, very similar to the existing get_volatile_registers_XXX. The
new methods are called get_saved_registers_XXX, where XXX is the register
type ("int", "address", "fpu" or "mm")
git-svn-id: trunk@38794 -
- xorq %reg,%reg (identical registers) is now changed to xorl %reg,%reg if doing so removes the REX prefix.
- movw %bx,%ax; andl $0xffff,%eax, for example, is now changed to movzwl %bx,%eax as long as a conditional operation doesn't follow 'and' (checks to see if the CPU flags are in use).
- movzbq and movzwq get optimised to movzbl and movzwl respectively if doing so removes the REX prefix.
- Removal of optimisation code that zero-extends from 32-bit to 64-bit, because there isn't actually a valid combination of opcodes for MOVZX that allows that (for registers,
just use MOV). This is not the case with MOVSX.
- movq is now optimised to movl even if the CPU flags are in use (this stops mov %reg,0 from being optimised to xor %reg,%reg if doing so breaks an algorithm that relies on them).
- Fixed typo in peephole message regarding movq to movl (it said movd instead).
- Made the peephole debug messages more consistent in formatting, some of which now have more detail.

retfq x86 instructions. These are variants of the ret instruction with the
return offset size set explicitly, e.g. retfw is a 16-bit far ret (i.e. pops
a 16-bit offset and a 16-bit segment), retfd is a 32-bit far ret (pops a
32-bit offset, followed by a 16-bit segment), etc.

(movs, cmps, scas, lods, stos, ins, outs) in the inline asm of the i8086, i386

* NEC V20/V30 instruction 'ins' (available only on the i8086 target, because it
is incompatible with 386+ instructions) renamed 'nec_ins', to avoid conflict
with the 186+ 'ins' instruction.
