to low addresses in case the target cpu/OS does not support this (enabled
for reads on AIX/PPC because on AIX the first 16KB are readable)

* in case of a jump/call to an AT_FUNCTION symbols on
systems_dotted_function_names platforms, prepend a dot to the symbol
name in assembler code

OS call before changes to the fpscr exception mask have any effect
* use OS calls to change FPU state on AIX, does not always propagate
otherwise
* don't use libc's log() on AIX, it wrongly returns a division-by-zero
exception in some cases

o the last bytes of records passed by value whose size is not a multiple
of the register size must be passed in the upper (leftmost) bytes of
a register
git-svn-id: trunk@20804 -
o .short/.long/.llong are automatically aligned to 2/4/8 byte multiples
by the AIX assembler (and for compatibility reasons, also by the
GNU assembler when targeting AIX) -> change to .vbyte statements
o .ascii does not allow non-ASCII characters in the AIX assembler
-> change to .byte sequences like gcc on AIX
git-svn-id: trunk@20803 -
pass on whether the symbol refers to code or data (important for
AIX weak symbols; note that AIX does not support undefined weak
external symbols, and FPC does not yet support weakly defining
non-external symbols, so this functionality isn't really used yet)
git-svn-id: trunk@20802 -
of the AVR-specific ifdef'ed variant
o since the only special character we use in mangled names on all platforms
is $, added a new field to tasminfo called "dollarsign" that holds the
character $'s should be replaced with (if it doesn't have to be replaced,
leave it at $)
git-svn-id: trunk@20801 -
* renamed some ppc64 stackframe offset constants to the same names as their
32 bit counterparts so they can be used in shared ppc code
git-svn-id: trunk@20794 -
* fixed code dealing with symbol+offsets on 64 bit platforms in
case of offsets > 32 bit (and to use smallint() typecasts
instead of lo(), since the return value of lo() depends on
the type passed in)
git-svn-id: trunk@20793 -
hence contains a dummy "main" that refers to the system unit
FPC_SYSTEMMAIN, which in turn jumps to the main program's PASCALMAIN
* we call FPC_SYSTEMMAIN instead of jumping to it like on Darwin, so that
the TOC gets set correctly
git-svn-id: trunk@20792 -
o doubles are aligned to 8 bytes outside records, but to 4 bytes
inside them
o same as for Darwin/PPC: if the first field of a record has 8 byte
alignment (including double!), then the struct itself gets 8 byte
alignment
