* Suppressed 2 unreachable code warnings.
* Now x86 compiler compiles without warnings and notes! It will be great to keep such state in future...
git-svn-id: trunk@11455 -
a) cpu64bitaddr, which means that we are generating a compiler which
will generate code for targets with a 64 bit address space/abi
b) cpu64bitalu, which means that we are generating a compiler which
will generate code for a cpu with support for 64 bit integer
operations (possibly running in a 32 bit address space, depending
on the cpu64bitaddr define)
All cpus which had cpu64bit set now have both the above defines set,
and none of the 32 bit cpus have cpu64bitalu set (and none will
compile with it currently)
+ pint and puint types, similar to aint/aword (not pword because that
that conflicts with pword=^word)
* several changes from aint/aword to pint/pword
* some changes of tcgsize2size[OS_INT] to sizeof(pint)
git-svn-id: trunk@10320 -
* removed addr_pic again for darwin, as you have to explicitly code
the relative address using a relsym instead of using an assembler
directive like @GOT there

- long lines were not wrapped.
- constants of type ait_comp_64bit output incorrectly.
- at end of file, current segment was not closed.
patch from Sergei Gorelkin
git-svn-id: trunk@9331 -
regloadedwithnewvalue() gave the wrong answer for this in case
candependonprevvalue was false (caused a wrong optimization in the
space() function of the rtl)
git-svn-id: trunk@8808 -
virtual register
* always add EBX to used_in_proc in case pi_needs_got, because it's
currently always used due to the geteipasebx call
* don't explicitly free the PIC register in the exitcode because
then the assembler optimizer assumes the load restoring it (ebx)
can be safely removed

to be made pic-safe (mainly accesses to the global default8087cw)
* At the same time also made the non-pic code abi-compliant (access
external data via indirect symbol pointers etc)
Darwin/i386 also puts the got into a virtual register (like
Darwin/ppc), a.o. because the register allocator fails to colour
a routine in aasmcpu.pas if we take away ebx from it.
git-svn-id: trunk@8657 -
suite compiled with -Cg compared to without -Cg)
+ support for using a virtual register as PIC/got base register
* moved got loading code from ncgutil to cgobj/cgcpu (can't test whether
it didn't break anything under linux/i386, because "make cycle OPT=-Cg"
was already broken due to the *prt*.as -> si_*.pp changes)
git-svn-id: trunk@8651 -
without relocations in sec_rodata_norel. It should be possible to make
this new section read-only on all platforms, although currently it
is only done for darwin, and for non-pic code written using the
-Aas assembler writer.
Most platforms also have a special section for "constant but with
relocations" data, but such a section is currently only used for
Darwin (others still use plain .data sections for that, like they
did before)
