From 998052555a65c42ac3cecc9262ef6bb31ea56ee8 Mon Sep 17 00:00:00 2001 From: Jack Carter Date: Sat, 25 Jan 2014 00:24:07 +0000 Subject: [PATCH] [Mips] TargetStreamer ELF flag Support for default and commandline options. This patch uses a common MipsTargetSteamer interface for both MipsAsmPrinter and MipsAsmParser for recording default and commandline driven directives that affect ELF header flags. It has been noted that the .ll tests affected by this patch belong in test/Codegen/Mips. I will move them in a separate patch. Also, a number of directives do not get expressed by AsmPrinter in the resultant .s assembly such as setting the correct ASI. I have noted this in the tests and they will be addressed in later patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200051 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/Mips/AsmParser/MipsAsmParser.cpp | 59 +++++++--- .../Mips/MCTargetDesc/MipsTargetStreamer.cpp | 14 +-- lib/Target/Mips/MipsAsmPrinter.cpp | 26 ++--- lib/Target/Mips/MipsAsmPrinter.h | 6 ++ lib/Target/Mips/MipsTargetStreamer.h | 6 +- test/MC/Mips/elf_eflags.ll | 102 +++++++++++++----- test/MC/Mips/elf_eflags.s | 20 ++-- test/MC/Mips/elf_st_other.ll | 5 +- 8 files changed, 162 insertions(+), 76 deletions(-) diff --git a/lib/Target/Mips/AsmParser/MipsAsmParser.cpp b/lib/Target/Mips/AsmParser/MipsAsmParser.cpp index aae2dcd16e7..35ad7680be6 100644 --- a/lib/Target/Mips/AsmParser/MipsAsmParser.cpp +++ b/lib/Target/Mips/AsmParser/MipsAsmParser.cpp @@ -21,6 +21,9 @@ #include "llvm/MC/MCSubtargetInfo.h" #include "llvm/MC/MCSymbol.h" #include "llvm/MC/MCTargetAsmParser.h" +#include "llvm/Support/ELF.h" +#include "llvm/Support/TargetRegistry.h" +#include "llvm/ADT/APInt.h" #include "llvm/Support/MathExtras.h" #include "llvm/Support/TargetRegistry.h" @@ -194,7 +197,6 @@ class MipsAsmParser : public MCTargetAsmParser { bool isEvaluated(const MCExpr *Expr);
