LLVM backend for 6502
The DwarfWriter expects DbgScopes and DIEs to behave themselves according to DwarfWriter's rules. However, inlined functions violate these rules. There are two different types of DIEs associated with an inlined function: an abstract instance, which has information about the original source code for the function being inlined; and concrete instances, which are created for each place the function was inlined and point back to the abstract instance. This patch tries to stay true to this schema. It bypasses how regular DbgScopes and DIEs are created and used when necessary. It provides special handling for DIEs of abstract and concrete instances. This doesn't take care of all of the problems with debug info for inlined functions, but it's a step in the right direction. For one thing, llvm-gcc generates wrong IR (it's missing some llvm.dbg intrinsics at the point where the function's inlined) for this example: #include <stdio.h> static __inline__ __attribute__((always_inline)) int bar(int x) { return 4; } void foo() { long long b = 1; int Y = bar(4); printf("%d\n", Y); } while clang generates correct IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71410 91177308-0d34-0410-b5e6-96231b3b80d8 |
