it was AT_NONE, which is invalid and should never be used
* explicitly pass the correct value for all calls to those methods elsewhere
in the compiler

Updated the code for a_load_const_cgpara in case it needed stack parameters. This was completely broken before. Now it should allow things to compile at least.

Fixed multiplication code generation for AVR controllers without mul instructions.
Added handling of the old interrupt procedure directive such that procedures with that use RETI instead of RET.
git-svn-id: trunk@31030 -
* omit entry/exit code, if no frame pointer is used, partly fixes issue #27842
* take advantage of adiw/sbiw
* make more often use of ldd/std
git-svn-id: trunk@30732 -
* handle function result of FPC_MUL_WORD correctly
* use mov ...,r1 to load a register with zero instead of clr ..., this might enable the register allocator to
coalesce these moves in the feature
* use tst/dec instead of cpi/sub in the shifting loops, this reduces register pressure on r16 and higher

Add support for .set and .weak on AVR.
Fix 64 bit negation on AVR.
Add cpu_capabilities to cpuinfo.pas and fixed some peephole optimizations.
Pass >4 byte parameters by reference.
git-svn-id: trunk@26943 -
Cleaned up parameter and funcretloc information generation in AVR paramanger, and made it closer to GCC's calling convention.
Fixed a number of codegenerator bugs generating invalid or broken instructions: CP operands were swapped, a number of instructions had immediate operands, and stack frame epilogue wasn't complete.
Added a bunch of peephole optimizations that clears the generated code up a lot.

+ x86 targets now directly call procedure variables located in references.
- a_call_ref method removed from tcg and thlcgobj.
git-svn-id: trunk@26666 -
that the type of the parameters can be determined automatically
o added compilerproc declarations for all helpers called in the compiler
via their assembler name, so we can look up the corresponding procdef
git-svn-id: trunk@23325 -
getintparaloc + adapted all call sites of getintparaloc. This
led to a number of additional, related changes:
o corrected the type information for some getintparaloc parameters
o don't allocate some intparalocs in cases they aren't used
o changed "const tvardata" parameter into "constref tvardata" for
fpc_variant_copy_overwrite to make pass-by-reference semantics
explicit
o moved a number of routines that now have to call find_system_type()
from cgobj to hlcgobj so that cgobj doesn't have to start depending
on the symtable unit
o added versions of the cpureg alloc/dealloc methods to hlcgobj that
call through to their cgobj counter parts, so we can call save/restore
the cpu registers before/after calling system helpers from hlcgobj
(not implemented in hlcgobj itself, because all basic register
allocator functionality is still part of cgobj/cgcpu)
