; 2: extern "C" void capture(int *p);
; 3: static __forceinline inline void will_be_inlined() {

[codeview] Add new directives to record inlined call site line info Summary: Previously we were trying to represent this with the "contains" list of the .cv_inline_linetable directive, which was not enough information. Now we directly represent the chain of inlined call sites, so we know what location to emit when we encounter a .cv_loc directive of an inner inlined call site while emitting the line table of an outer function or inlined call site. Fixes PR29146. Also fixes PR29147, where we would crash when .cv_loc directives crossed sections. Now we write down the section of the first .cv_loc directive, and emit an error if any other .cv_loc directive for that function is in a different section. Also fixes issues with discontiguous inlined source locations, like in this example: volatile int unlikely_cond = 0; extern void __declspec(noreturn) abort(); __forceinline void f() { if (!unlikely_cond) abort(); } int main() { unlikely_cond = 0; f(); unlikely_cond = 0; } Previously our tables gave bad location information for the 'abort' call, and the debugger wouldn't snow the inlined stack frame for 'f'. It is important to emit good line tables for this code pattern, because it comes up whenever an asan bug occurs in an inlined function. The __asan_report* stubs are generally placed after the normal function epilogue, leading to discontiguous regions of inlined code.

[PR27284] Reverse the ownership between DICompileUnit and DISubprogram. Currently each Function points to a DISubprogram and DISubprogram has a scope field. For member functions the scope is a DICompositeType. DIScopes point to the DICompileUnit to facilitate type uniquing. Distinct DISubprograms (with isDefinition: true) are not part of the type hierarchy and cannot be uniqued. This change removes the subprograms list from DICompileUnit and instead adds a pointer to the owning compile unit to distinct DISubprograms. This would make it easy for ThinLTO to strip unneeded DISubprograms and their transitively referenced debug info. Motivation ---------- Materializing DISubprograms is currently the most expensive operation when doing a ThinLTO build of clang. We want the DISubprogram to be stored in a separate Bitcode block (or the same block as the function body) so we can avoid having to expensively deserialize all DISubprograms together with the global metadata. If a function has been inlined into another subprogram we need to store a reference the block containing the inlined subprogram. Attached to https://llvm.org/bugs/show_bug.cgi?id=27284 is a python script that updates LLVM IR testcases to the new format. http://reviews.llvm.org/D19034 <rdar://problem/25256815> llvm-svn: 266446
