bool HasSingleParameterDotFile
True if the target has a single parameter .file directive, this is true for ELF targets.
Definition: MCAsmInfo.h:283
StringRef PrivateLabelPrefix
This prefix is used for labels for basic blocks.
Definition: MCAsmInfo.h:132
Compute iterated dominance frontiers using a linear time algorithm.
Definition: AllocatorList.h:24
bool shouldOmitSectionDirective(StringRef SectionName) const override
Return true if the .section directive should be omitted when emitting SectionName.
const char * SeparatorString
This string, if specified, is used to separate instructions from each other when on the same line...
Definition: MCAsmInfo.h:110
bool HasNoDeadStrip
True if this target supports the MachO .no_dead_strip directive.
Definition: MCAsmInfo.h:291
StringRef CommentString
This indicates the comment character used by the assembler.
Definition: MCAsmInfo.h:114
bool UsesELFSectionDirectiveForBSS
This is true if this target uses ELF '.section' directive before the '.bss' one.
Definition: MCAsmInfo.h:221
bool HasAggressiveSymbolFolding
False if the assembler requires that we use.
Definition: MCAsmInfo.h:263
bool StackGrowsUp
True if target stack grow up. Default is false.
Definition: MCAsmInfo.h:73
bool SunStyleELFSectionSwitchSyntax
This is true if this target uses "Sun Style" syntax for section switching ("#alloc,#write" etc) instead of the normal ELF syntax (,"a,w") in .section directives.
Definition: MCAsmInfo.h:216
virtual bool shouldOmitSectionDirective(StringRef SectionName) const
Return true if the .section directive should be omitted when emitting SectionName.
Definition: MCAsmInfo.cpp:119
ArchType getArch() const
getArch - Get the parsed architecture type of this triple.
Definition: Triple.h:285
const char * InlineAsmStart
If these are nonempty, they contain a directive to emit before and after an inline assembly statement...
Definition: MCAsmInfo.h:142
bool COMMDirectiveAlignmentIsInBytes
True is .comm's and .lcomms optional alignment is to be specified in bytes instead of log2(n)...
Definition: MCAsmInfo.h:267
bool SupportsDebugInformation
True if target supports emission of debugging information.
Definition: MCAsmInfo.h:332
const char * WeakRefDirective
This directive, if non-null, is used to declare a global as being a weak undefined symbol...
Definition: MCAsmInfo.h:302
Triple - Helper class for working with autoconf configuration names.
Definition: Triple.h:44
const char * InlineAsmEnd
Definition: MCAsmInfo.h:143
