regloadedwithnewvalue() gave the wrong answer for this in case
candependonprevvalue was false (caused a wrong optimization in the
space() function of the rtl)

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.

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)

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)

- {$intpromotion common_type} or -CIcommon_type switches to common type promotion.
- {$intpromotion native_integer} or -CIcommon_type switches to current behaviour.
- Default in tp mode is common_type, native_integer in other modes
- Compiler can cycle with -CIcommon_type
- Still needs checking on other architectures than i386
git-svn-id: trunk@8118 -
a structure whose address is passed by the caller (the caller is
responsible there to remove the address from the stack, unlike on
e.g. linux/i386 and darwin/i386) (mantis #9013)
git-svn-id: trunk@7667 -
the flags are read afterwards (broke shldl/sub/sbb sequence generated
for 64 bit "*2", which appears in bitpacked size calculation)
