◆ addPgProfilingLinkArgs()

static void addPgProfilingLinkArgs ( const Darwin D,

◆ addSectalignToPage()

static void addSectalignToPage ( const ArgList &  Args,
ArgStringList &  CmdArgs,
StringRef  Segment,
StringRef  Section

static

Add a sectalign directive for Segment and Section to the maximum expected page size for Darwin.

On iPhone 6+ the max supported page size is 16K. On macOS, the max is 4K. Use a common alignment constant (16K) for now, and reduce the alignment on macOS if it proves important.

◆ shouldLinkerNotDedup()

static bool shouldLinkerNotDedup ( bool  IsLinkerOnlyAction,
const ArgList &  Args

static

Pass -no_deduplicate to ld64 under certain conditions:

  • Either -O0 or -O1 is explicitly specified
  • No -O option is specified and this is a compile+link (implicit -O0)

Also do not add -no_deduplicate when no -O option is specified and this is just a link (we can't imply -O0)
