class MCSectionMachO

Declaration

class MCSectionMachO : public MCSection { /* full declaration omitted */ };

Description

This represents a section on a Mach-O system (used by Mac OS X). On a Mac system, these are also described in /usr/include/mach-o/loader.h.

Methods

¶static std::string ParseSectionSpecifier(
    llvm::StringRef Spec,
    llvm::StringRef& Segment,
    llvm::StringRef& Section,
    unsigned int& TAA,
    bool& TAAParsed,
    unsigned int& StubSize)

Description

Parse the section specifier indicated by "Spec". This is a string that can appear after a .section directive in a mach-o flavored .s file. If successful, this fills in the specified Out parameters and returns an empty string. When an invalid section specifier is present, this returns a string indicating the problem. If no TAA was parsed, TAA is not altered, and TAAWasSet becomes false.

Declared at: llvm/include/llvm/MC/MCSectionMachO.h:71

Parameters

llvm::StringRef Spec

llvm::StringRef& Segment

llvm::StringRef& Section

unsigned int& TAA

bool& TAAParsed

unsigned int& StubSize

¶void PrintSwitchToSection(
    const llvm::MCAsmInfo& MAI,
    const llvm::Triple& T,

Declared at: llvm/include/llvm/MC/MCSectionMachO.h:78

Parameters

¶bool UseCodeAlign() const

Description

Return true if a .align directive should use "optimized nops" to fill instead of 0s.
