16cb409fbf LLVM: separate as_clang_llvm_darwin 
The Darwin local label prefix ('L') is different from that on most other
platforms ('.L). While LLVM generally handles that for us, for inline
assembly it's still FPC's job to adhere to the target conventions.

edbddec98a llvmdbg: diflags/dispflags fixes 
Fix MainSubprogram flag for older LLVM versions, as it was a plain flag rather
than a subprogram flag there.

Added visibility flags for procdefs (public/private/protected)

Write flags as enum rather than integer to avoid issues with changing values
across different LLVM versions

816ab7ffcc llvm metadata: counter per unit rather than globally

9b280db2b1 dbgllvm: add scopeLine attribute for function debug info 
Ensures that breaking on the function correctly sets the breakpoint on the
first source line of the function (rather than potentially in the prologue
without line information)

13055bb58a llvmtype: ensure all processed defs get recorded

f832444eaa LLVM lineinfo: fix nolineinfo generation 
LLVM requires line info metadata for all call instructions that may potentially
be inlined. So attach one to all call instructions in nolineinfo regions, but
set their line number to 0 (same as what clang does)
 2022-05-13 22:49:02 +02:00
Jonas Maebe
40418f5b3d dbgllvm: remove restriction to only write struct procdef in context of struct 
Does not make a difference for LLVM since all debug info for procdefs is
assigned to the definition instructions for the procdef anyway, and avoids
issues when only generating line info (in that case the structs will never
be processed, but we still have to generate the basic debug info for their
procdefs to provide a scope for their line info)
 2022-05-13 22:49:02 +02:00

6cacd9c824 llvmdbg: initial version based on dbgdwarf

229eb93e72 tnodeuitls: merge GenerateObjCImageInfo into InsertObjectInfo 
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)
