class MCXCOFFStreamer

Declaration

class MCXCOFFStreamer : public MCObjectStreamer { /* full declaration omitted */ };

Description

Streaming object file generation interface. This class provides an implementation of the MCStreamer interface which is suitable for use with the assembler backend. Specific object file formats are expected to subclass this interface to implement directives specific to that file format or custom semantics expected by the object writer implementation.

void emitXCOFFRefDirective(llvm::StringRef Name)

Description

Emit a XCOFF .ref directive which creates R_REF type entry in the relocation table for one or more symbols.

Declared at: llvm/include/llvm/MC/MCXCOFFStreamer.h:35

Parameters

llvm::StringRef Name

void emitXCOFFRenameDirective(
    const llvm::MCSymbol* Name,

Declared at: llvm/include/llvm/MC/MCXCOFFStreamer.h:39

Parameters

const llvm::MCSymbol* Name
- The name used internally in the assembly for references to the symbol.
llvm::StringRef Rename
- The value to which the Name parameter is changed at the end of assembly.

Description

Emit a symbol's linkage and visibility with a linkage directive for XCOFF.

Declared at: llvm/include/llvm/MC/MCXCOFFStreamer.h:32

Parameters

llvm::MCSymbol* Symbol
- The symbol to emit.
llvm::MCSymbolAttr Linkage
- The linkage of the symbol to emit.
llvm::MCSymbolAttr Visibility
