compiler's internal assembly representation. It is not yet generated by the
compiler and is only implemented properly in the NASM writer (but will
eventually be implemented in the other assembler writers as well, including
the internal assembler). In the future, it is intended to allow:
1) catching instructions, generated by the compiler and not supported by the
target CPU, due to a bug in the code generator
2) allowing a different instruction set to be used in inline asm blocks (I'm
planning a new directive for that - {$asmcpu XXX}), because the code
generator will be able to switch target CPU in the middle of the asm output
stream

- Fixed access to symbols with offset.
- Always use register R9 for GOT pointer to prevent bugs when free register limit is reached in a function.
- GOT is not needed for function calls by name.

that we can use assembler writers with different conventions from the
currently set target_asm (e.g. an x86 assembler writer for inline assembly
in LLVM IR)
git-svn-id: trunk@31628 -
* generate code to load the TOC register if it's required, and
emit the the ".localentry" directive to indicate to the linker
where the actual function body starts
* support the ".localentry" directive in the ppc64 assembler reader
o disable the fpc_qword_to_double() assembler implementation for
ELFv2, because we can't manually insert the .localentry directive
before the stack allocation code
* perform indirect calls on ppc64 via R12 in ncgcal, as R12 needs to
contain the function address on entry on ppc64/ELFv2 (and it's
a volatile register, so there's no problem with always using
it)
git-svn-id: trunk@30198 -
names, and disabled them for ppc64 ELFv2
* disabling those also disables the function descriptors, so use the
_CALL_ELF compiler variable to check whether there is in fact a
function descriptor
git-svn-id: trunk@30196 -
to free up space for more ait_* types in taitype (can't have
more than 32 because they have to fit in a small set)
o factored out writing of floating point numbers as an array of
byte in the external assemblers
git-svn-id: branches/hlcgllvm@28105 -
the value set by -Ch or the second parameter to the $M directive). This is
equivalent to the heapmin value in Turbo Pascal 7 and ensures that the program
has at least this amount of heap space available (otherwise DOS will show a
'not enough memory' error and will refuse to load the program).

itself (instead of having a fixed 16k stack in the startup code). This allows
setting the stack size in these models with the -Cs option.
git-svn-id: trunk@27820 -
otherwise data in initialised packed records gets aligned wrongly. This
should probably also be done for other targets that automatically
align .short/.long/...
git-svn-id: trunk@27600 -
Add support for .set and .weak on AVR.
Fix 64 bit negation on AVR.
Add cpu_capabilities to cpuinfo.pas and fixed some peephole optimizations.
Pass >4 byte parameters by reference.
git-svn-id: trunk@26943 -
* Change MIPS jump tables in PIC mode to use gp-relative constants, making them ABI-compliant and not requiring dynamic relocations.
git-svn-id: trunk@26886 -
* aggas.pas, TGNUAssembler.WriteTree.doalign:
instead of strangely checking for the previous instruction always use .balignw if the previous code was code and we should not use a specific instruction
