bool HasSingleParameterDotFile
True if the target has a single parameter .file directive, this is true for ELF targets.
Definition: MCAsmInfo.h:282
const char * WeakDirective
Used to declare a global as being a weak symbol. Defaults to ".weak".
Definition: MCAsmInfo.h:297
This class represents lattice values for constants.
Definition: AllocatorList.h:23
Not a valid directive.
Definition: MCDirectives.h:19
const char * Data64bitsDirective
Definition: MCAsmInfo.h:192
const char * ZeroDirective
This should be set to the directive used to get some number of zero bytes emitted to the current sect...
Definition: MCAsmInfo.h:173
bool SupportsQuotedNames
If this is true, symbol names with invalid characters will be printed in quotes.
Definition: MCAsmInfo.h:160
const char * GlobalDirective
This is the directive used to declare a global entity.
Definition: MCAsmInfo.h:240
unsigned CalleeSaveStackSlotSize
Size of the stack slot reserved for callee-saved registers, in bytes.
Definition: MCAsmInfo.h:66
bool HasDotTypeDotSizeDirective
True if the target has .type and .size directives, this is true for most ELF targets.
Definition: MCAsmInfo.h:278
const char * AsciiDirective
This directive allows emission of an ascii string with the standard C escape characters embedded into...
Definition: MCAsmInfo.h:178
StringRef CommentString
This indicates the comment character used by the assembler.
Definition: MCAsmInfo.h:113

These directives are used to output some unit of integer data to the current section.
Definition: MCAsmInfo.h:189
bool HasFunctionAlignment
Definition: MCAsmInfo.h:274
MCSymbolAttr HiddenVisibilityAttr
This attribute, if not MCSA_Invalid, is used to declare a symbol as having hidden visibility...
Definition: MCAsmInfo.h:317
ArchType getArch() const
getArch - Get the parsed architecture type of this triple.
Definition: Triple.h:294
const char * AscizDirective
If not null, this allows for special handling of zero terminated strings on this target.
Definition: MCAsmInfo.h:183
NVPTXMCAsmInfo(const Triple &TheTriple)
const char * InlineAsmStart
If these are nonempty, they contain a directive to emit before and after an inline assembly statement...
Definition: MCAsmInfo.h:141
bool SupportsDebugInformation
True if target supports emission of debugging information.
