const char * WeakRefDirective
This directive, if non-null, is used to declare a global as being a weak undefined symbol.
Definition: MCAsmInfo.h:390
bool HasDotTypeDotSizeDirective
True if the target has .type and .size directives, this is true for most ELF targets.
Definition: MCAsmInfo.h:367
bool UsesELFSectionDirectiveForBSS
This is true if this target uses ELF '.section' directive before the '.bss' one.
Definition: MCAsmInfo.h:314
bool SupportsDebugInformation
True if target supports emission of debugging information.
Definition: MCAsmInfo.h:423
bool DwarfUsesRelocationsAcrossSections
True if Dwarf2 output generally uses relocations for references to other .debug_* sections.
Definition: MCAsmInfo.h:437
bool HasSingleParameterDotFile
True if the target has a single parameter .file directive, this is true for ELF targets.
Definition: MCAsmInfo.h:371
bool IsLittleEndian
True if target is little endian. Default is true.
Definition: MCAsmInfo.h:79
unsigned CodePointerSize
Code pointer size in bytes. Default is 4.
