o made all (non-abstract) tdef and tsym constructors virtual
o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
class
o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
class from the base classes, and initialises the c*def/c*sym classes with
them. This is done so that the llvm target will be able to derive from
the tcpu*def/sym classes without umpteen ifdefs, and it also means that
the WPO can devirtualise everything because the c* variables are only
initialised with one class type
o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
calls
git-svn-id: trunk@27361 -
required for the LLVM support (LLVM parameter support is not yet
included)
* always return the function return loc from a_call*, again as required
for the LLVM support
git-svn-id: branches/hlcgllvm@26992 -
* Change MIPS jump tables in PIC mode to use gp-relative constants, making them ABI-compliant and not requiring dynamic relocations.
git-svn-id: trunk@26886 -
do_spill_replace routines, will be necessary by llvm register
allocator to determine the tdef corresponding to that register
* replaced uses of taicpu with tai_cpu_abstract_sym in the register
allocator so that it can work both with taicpu and taillvm instructions
git-svn-id: branches/hlcgllvm@26043 -
cgobj.pas, tcg:
* g_save_registers: add the amount of used address registers to size as well
* g_save_registers: save all used address registers
* g_restore_registers: restore all stored address registers
m68k/cpubase.pas:
* rename saved_standard_address_registers to saved_address_registers
all other platform's cpubase.{inc,pas} (except alpha, ia64 and vis which are not up to date):
* add a saved_address_registers variable with one entry of RS_INVALID
At least a "make fullcycle" did complete.
git-svn-id: trunk@25664 -
* Deallocate GP save temp in epilogue to avoid warnings when compiled with -dEXTDEBUG
* g_concatcopy: don't check alignment, this allows single byte or word locations to be copied with 2 instructions. Larger unaligned references are supposed to be handled in g_concatcopy_unaligned instead.
git-svn-id: trunk@25147 -
* Use fpc_[int64|qword]_to_double instead of [int64|qword]_to_float64, makes RTL no longer dependent on softfloat code.
* Move 32-bit values from integer registers to FPU registers without using memory.
* Fixed branching, was still using a macro and delay slot was missing.

The difference in branch instruction formats is isolated in function JumpTargetOp, it is a plain function rather than a virtual method, so it can be easily inlined and, after inlining, produces the same code for non-MIPS targets as it was before change.
git-svn-id: trunk@25033 -
* Moved jump tables into data segment. For disassembly-based stack unwinding to work properly, MIPS ABI expects text segment to contain instructions only.
git-svn-id: trunk@24904 -
+ Implemented subset of "spill replace" functionality, replacing moves from/to spilled registers with loads/stores to spill locations. This helps to reduce amount of instructions.
git-svn-id: trunk@24900 -
* Output registers of type R_SPECIALREGISTER as numbers.
+ For MTC0/MFC0 instructions, set type of first operand to R_SPECIALREGISTER, since it designates a coprocessor register.
git-svn-id: trunk@24799 -
contains the tcgsize of the entire parameter rather than only of
what is left (-> calculate it from the remaining parameter length)
git-svn-id: trunk@24776 -
- removed mips_cpu variable and cpu_mips_default CPU type.
* globals.pas: default CPU type changed to MIPS2, this is what was passed to assembler before.
git-svn-id: trunk@24643 -
- references cannot be in brackets
- registers are only prefixed by dollar, never by percent
- syntax x@LO is not supported, must be %lo(x).
git-svn-id: trunk@24633 -
* reworked condition codes, changed BC1T and BC1F from separate instructions to condition jumps.
- removed A_P_SW, A_P_LW and A_SPARC8UNIMP
+ support '.set at' and '.set noat' directives
+ prepare to support bgtz,bgez,bltz,blez instructions.
git-svn-id: trunk@24631 -
+ Implemented overflow checking for unsigned 32-bit addition and subtraction.
* Use optimize_op_const instead of custom optimizations.
* Change AND/OR/XOR into ANDI/ORI/XORI if they use immediate operands, and use correct range for these immediate operands, must be 0..65535 unlike -32768..32767 for arithmetic operations.
* Don't treat AND/OR/XOR as macros, no longer necessary.
* Don't treat BEQ/BNE as macros either.
git-svn-id: trunk@24445 -
* TCGMIPS.a_load_reg_reg: generate CPU instructions instead of macros
* TCGMIPS.a_cmp_const_reg_label: load constant using a_load_const_reg instead of LI macro (it may also end up with LI, but tries to optimize when possible).
- removed unused variables.
git-svn-id: trunk@24418 -
* shorter by 280 lines
* generates actual instructions instead of macros
* uses immediate operands for constants when possible
* 64-bit and float comparisons use LOC_JUMP as location
git-svn-id: trunk@24236 -
- Removed TMIPSProcInfo.needs_frame_pointer, it duplicates pi_needs_stackframe flag.
- Don't save RA for leaf procedures.
* GP is caller-saved register, it does not need saving/restoring as nonvolatile registers. Handle its restore position as a "normal" temp, whose offset is known before secondpass. This allows to handle PIC calls without involving GAS macro processing.
git-svn-id: trunk@23885 -
+ Favor 'weak' parameter in a_call_name of both thlcgmips and TCGMIPS.
* make_simple_ref and a_loadaddr_ref_reg: require input references to be 'raw' (no refaddr=addr_pic, etc) and do not use GP as base/index. If it's not true, raise an internal error. When addr_pic_call16 or so needs to be generated, it must be done without calling the mentioned methods.
* thlcgmips.a_call_name: generate PIC sequence for procedures declared as 'external', instead of 'cdecl', this is more correct because ABI has only one calling convention.
- make_simple_ref_fpu removed, there's no reason to handle references to floating-point data in different way.
- a_loadaddr_ref_cgpara override also removed, generic method does the job just well.
- thlcgmips.a_call_ref and a_call_reg overrides removed because indirect calls are now always done using $t9.
git-svn-id: trunk@23698 -
* Abort if attempting to emit a call without pi_do_call flag set, because the outgoing parameter area determines layout of temps and therefore cannot be created/changed during pass 2.
* Bypass g_concatcopy_move if procedure is a leaf one, due to the restriction mentioned above.
git-svn-id: trunk@23644 -
* Parameters passed in registers are no longer forced to stack, therefore assembler routines using 'lw' instruction to load such parameters must have it changed to 'move' (tb0072.pp).
