8971103a00 * use bit_set_reg_reg also to clear single bits in thlcgobj.a_load_regconst_subsetref_intern 2024-03-26 14:46:01 +01:00

49cb7b2564 LLVM: use llvm.dbg.declare instead of llvm.dbg.addr for variable declarations 
Even though it's supposedly deprecated, clang also still uses it and without
the declaration ranges of local variables are sometimes cut off

5486182f56 + introduced thlcgobj.a_jmp_always_pascal_goto - same as .a_jmp_always, but generated by a pascal goto statement 2023-10-22 04:12:59 +03:00
Nikolay Nikolov
9b8af14f47 + introduced [hl]cg.a_label_pascal_goto_target. It is similar to [hl]cg.a_label 
and is called by the code generator, when the label generated is the result of
  a Pascal label.

ee0ad3ff86 thlcgobj.g_undefined_ok: new method 
Specify that a register's contents may be undefined because of previous
operations (e.g. shifting by more bits than the register has, whose result
depends on the target architecture), but that the code generator will
later on ensure that if this is the case, that result will be overwritten/
masked.

a76038e1d1 hlcgobj: new getlocal and recordnewsymloc methods 
Call hlcg.getlocal instead of tg.getlocal when used for actual parameters/local
variables. Has an extra tsym parameter, which will enable the LLVM backend to
insert debug information.

Call hlcg.recordnewsymloc when the location of a (local/para) symbol changes,
so debug info tracking can be updated (only done for LLVM currently)

3c58f26e83 * thlcgwasm.g_checkexceptions renamed .g_maybe_checkforexceptions, added also as 
an empty virtual method in thlcgobj and modified the WebAssembly
  implementation, so that it can be called from any exceptions mode (so it
  emits no code in exception modes that don't require it, instead of generating
  an internal error). This will allow .g_maybe_checkforexceptions to be called
  from the generic parts of the code generator, after calls to systemprocs that
  could raise an exceptions.

9d1c814387 * Added the thlcgobj.a_load_undefined_cgpara() method to pass an undefined value as a parameter to a routine. The generic version passes the 0/nil value if the parameter's location is not a register. 
* Use a_load_undefined_cgpara() to load values for unused parameters.

* introduced op_reg,op_ref,op_subsetreg,op_subsetref and op_loc for the unary
  operations only (OP_NEG,OP_NOT)

e56b58c2b0 * factored out checks whether a procdef's symbol needs to be global, and 
the generation of the procdef's asmsymbols

3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/ 
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.

322a717c44 * support for handling subsetrefs with bitlen > AIntBits in a_load_subsetref_reg() and 
a_load_const/reg_subsetref() (needed for handling 32 bit platforms using a purely
    high level code generator like LLVM's, and may also improve the situation for
    16 bit platforms)
   o can probably be optimized to split them into parts that cover partial word loads
     and complete word loads (to reduce useless merging)
