From 0709a7bd1a75191a13580ca2a505fa0f7c4326bd Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Thu, 21 May 2015 19:20:38 +0000 Subject: Move alignment from MCSectionData to MCSection. This starts merging MCSection and MCSectionData. There are a few issues with the current split between MCSection and MCSectionData. * It optimizes the the not as important case. We want the production of .o files to be really fast, but the split puts the information used for .o emission in a separate data structure. * The ELF/COFF/MachO hierarchy is not represented in MCSectionData, leading to some ad-hoc ways to represent the various flags. * It makes it harder to remember where each item is. The attached patch starts merging the two by moving the alignment from MCSectionData to MCSection. Most of the patch is actually just dropping 'const', since MCSectionData is mutable, but MCSection was not. llvm-svn: 237936 --- llvm/lib/CodeGen/AsmPrinter/DwarfFile.cpp | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'llvm/lib/CodeGen/AsmPrinter/DwarfFile.cpp') diff --git a/llvm/lib/CodeGen/AsmPrinter/DwarfFile.cpp b/llvm/lib/CodeGen/AsmPrinter/DwarfFile.cpp index 1d6298c228a..10b58d4e86a 100644 --- a/llvm/lib/CodeGen/AsmPrinter/DwarfFile.cpp +++ b/llvm/lib/CodeGen/AsmPrinter/DwarfFile.cpp @@ -50,7 +50,7 @@ void DwarfFile::addUnit(std::unique_ptr U) { void DwarfFile::emitUnits(bool UseOffsets) { for (const auto &TheU : CUs) { DIE &Die = TheU->getUnitDie(); - const MCSection *USection = TheU->getSection(); + MCSection *USection = TheU->getSection(); Asm->OutStreamer->SwitchSection(USection); TheU->emitHeader(UseOffsets); @@ -120,7 +120,7 @@ unsigned DwarfFile::computeSizeAndOffset(DIE &Die, unsigned Offset) { return Offset; } -void DwarfFile::emitAbbrevs(const MCSection *Section) { +void DwarfFile::emitAbbrevs(MCSection *Section) { // Check to see if it is worth the effort. if (!Abbreviations.empty()) { // Start the debug abbrev section. @@ -130,8 +130,7 @@ void DwarfFile::emitAbbrevs(const MCSection *Section) { } // Emit strings into a string section. -void DwarfFile::emitStrings(const MCSection *StrSection, - const MCSection *OffsetSection) { +void DwarfFile::emitStrings(MCSection *StrSection, MCSection *OffsetSection) { StrPool.emit(*Asm, StrSection, OffsetSection); } -- cgit v1.2.3
