Public Member Functions
bool	isUnallocatedFunctionInfo () const
	Returns true if this is function info has not yet been used in a .cv_func_id or .cv_inline_site_id directive.
bool	isInlinedCallSite () const
	Returns true if this represents an inlined call site, meaning ParentFuncIdPlusOne is neither zero nor ~0U.

Public Attributes
unsigned	ParentFuncIdPlusOne = 0
	If this represents an inlined call site, then ParentFuncIdPlusOne will be the parent function id plus one.

MCSection *	Section = nullptr
	The section of the first .cv_loc directive used for this function, or null if none has been seen yet.
DenseMap< unsigned, LineInfo >	InlinedAtMap
	Map from inlined call site id to the inlined at location to use for that call site.

Detailed Description

Information describing a function or inlined call site introduced by .cv_func_id or .cv_inline_site_id.

Accumulates information from .cv_loc directives used with this function's id or the id of an inlined call site within this function or inlined call site.

isInlinedCallSite()

bool llvm::MCCVFunctionInfo::isInlinedCallSite ( ) const

inline

Returns true if this represents an inlined call site, meaning ParentFuncIdPlusOne is neither zero nor ~0U.

isUnallocatedFunctionInfo()

bool llvm::MCCVFunctionInfo::isUnallocatedFunctionInfo ( ) const

inline

Returns true if this is function info has not yet been used in a .cv_func_id or .cv_inline_site_id directive.

InlinedAt

LineInfo llvm::MCCVFunctionInfo::InlinedAt

Definition at line 114 of file MCCodeView.h.

InlinedAtMap

DenseMap<unsigned, LineInfo> llvm::MCCVFunctionInfo::InlinedAtMap

Map from inlined call site id to the inlined at location to use for that call site.

Call chains are collapsed, so for the call chain 'f -> g -> h', the InlinedAtMap of 'f' will contain entries for 'g' and 'h' that both list the line info for the 'g' call site.

ParentFuncIdPlusOne

unsigned llvm::MCCVFunctionInfo::ParentFuncIdPlusOne = 0

If this represents an inlined call site, then ParentFuncIdPlusOne will be the parent function id plus one.

If this represents a normal function, then there is no parent, and ParentFuncIdPlusOne will be FunctionSentinel. If this struct is an unallocated slot in the function info vector, then ParentFuncIdPlusOne will be zero.

Section

MCSection* llvm::MCCVFunctionInfo::Section = nullptr

The section of the first .cv_loc directive used for this function, or null if none has been seen yet.
