support the stabx as understood by gdb, which is a mixture of regular
stabs and stabx (e.g., class/object definitions are completely different
in real stabx). This means that gdb can be used to debug aix programs,
but the native dbx will complain about lots of debug information
constructs

on AIX. Adding ".align" statements only align relative to the section
start, but does not influence the alignment of the section itself
git-svn-id: trunk@20835 -
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)
git-svn-id: trunk@20832 -
* 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
git-svn-id: trunk@20829 -
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
