LLVM needs to insert the Objective-C image info into the general object info
metadata. This way we don't need to store a reference to that metadata so
as to add extra data to it later (tnodeutils is never instantiated, it only
contains class methods)
private_extern (or plain global in case of PECOFF, as the effect is
the same there): visible across object files, but they become local
when linked into a binary/library. This enables cross-unit inlining
of functions accessig implementation-only symbols.

add such symbols to the pseudo-arrays llvm.compiler.used or llvm.used
depending on their nature (fixes compiling Objective-C programs with
optimization, and keeps the FPC ident in the linked binary)
git-svn-id: trunk@35041 -
symbol is defined
o removed all places where AB_INDIRECT symbols were explicitly generated
o only generate AB_INDIRECT symbols for AT_DATA on systems_indirect_var_imports
o for some symbols an indirect symbol is always required (because they are
dereferenced by code in RTL units) -> use new AT_DATA_FORCEINDIRECT type
git-svn-id: trunk@34165 -
tasmdata.DefineAsmSymbol() and all routines that call it
o will be used to automatically generate AB_INDIRECT sybols when
necessary

defined) or a declaration (external symbol), instead of deriving it from
from the bind of the tasmsymbol. The reason is that with module-level
inline assembly, some locally implemented functions (in pure assembler)
won't have an LLVM IR body
git-svn-id: trunk@31629 -
handle recursive record references (rec= record prec: ^rec)
o llvm unfortunately does not support recursive references to array types
or function pointers, so those will currently still result in endless
recursion when the compiler tries to write them out. Solving those
will require a lot of typecasting in the generated code
git-svn-id: trunk@30675 -
typed constant data
o llvm declarations now get an extra "initdata" list that contains the
typed constant data associated with this declaration (if any)
git-svn-id: branches/hlcgllvm@28111 -
generate declarations when external symbols are referred in a taillvm
instruction
* added "declared" field to tasmsymbol for llvm to make avoid declaring a
symbol multiple times (harmless, but unnecessary)
* all kinds of declarations/definitions are now handled using the new
taillvmdecl, the old separate types have been removed
git-svn-id: branches/hlcgllvm@27010 -
overridden by the llvm target
* override a bunch of other ngenutil methods with empty stubs for things
that are not yet supported when targeting llvm
