60e77de115 LLVM: remove flags used to support older LLVM versions 2024-01-08 19:33:28 +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

00a5d30300 LLVM: remove use of getelementptr in make_simple_ref_ptr 
We cannot safely infer whether it needs to be indirect or not there,
it should be done at a higher level if appropriate.

ab581c5c30 LLVM: override thlcgobj.g_undefined_ok 
Uses the freeze instruction available in LLVM 10.0+. If we don't freeze undef/
poison values before using them in a calculation (even if that calculation is
something like "and 0", which masks the result completely), the result will
still be undef/poison and will keep propagating.

657b9a6203 LLVM: support for -Sv (manual vector usage) 
Override register type for vectors to "integer registers" because we don't
use mmregister on LLVM (they're all virtual, so it doesn't matter)

25999ad8ff llvm: support for opaque pointers 
Will be the default starting with LLVM 15, and required with LLVM 16.
Tested with LLVM 14 and '-mllvm -opaque-pointers'. See
https://releases.llvm.org/14.0.0/docs/OpaquePointers.html for more
information.

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)

a76085e463 tllvmcallpara: record whether it's passed to metadata

e.g. for the first argument to llvm.dbg.addr

80282d6eff * llvm: only set custom parameter alignments for byval parameters, the rest 
is handled automatically by llvm (and since llvm 11.0 you get an error if
    you specify an alignment for them anyway)

9bd33f7a45 + support for LLVM metadata constant string parameters 
o they are implemented as a new metadata register class, whereby the
     subregister indicates the metadata type (currently always a string)
     and the superregister is an index in the metadata array (which
     contains the strings). LLVM metadata can only be passed as parameters
     to intrinsics in bitcode, so moves of metadata into other registers
     triggers internal errors and when moving them into parameters, we
     replace the parameter's register with the metadata register (and look
     up the corresponding string when writing out the bitcode)

1dee4c41dd - removed "cmp 0/1, pasbool1" optimization for llvm because this discards 
the upper 7 bits of the boolean, while other platforms take it into
    account (even though they're technically always required to be 0, and
    the value is undefined if they're not)

4cd6f59bc3 * changed create_hlcodegen into a procvar, so that we don't have to insert 
hlcgllvm in the uses clause of every unit that calls create_hlcodegen
   o prevents dependency cycles that can cause llvm codegen units to init
     before the cpu variants, which is bad since the llvm versions have to
     override the cpu variants in their init code (+ added checks in the
     init code that they are in fact initialised later)
