From 18d49acdab79d6f0966b47182b6c3a2ba3d9f80f Mon Sep 17 00:00:00 2001 From: Nico Rieck Date: Wed, 10 Apr 2013 23:28:17 +0000 Subject: MC: Support COFF image-relative MCSymbolRefs Add support for the COFF relocation types IMAGE_REL_I386_DIR32NB and IMAGE_REL_AMD64_ADDR32NB for 32- and 64-bit respectively. These are similar to normal 4-byte relocations except that they do not include the base address of the image. Image-relative relocations are used for debug information (32-bit) and SEH unwind tables (64-bit). A new MCSymbolRef variant called 'VK_COFF_IMGREL32' is introduced to specify such relocations. For AT&T assembly, this variant can be accessed using the symbol suffix '@imgrel'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179240 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/MC/MCExpr.cpp | 3 +++ 1 file changed, 3 insertions(+) (limited to 'lib/MC/MCExpr.cpp') diff --git a/lib/MC/MCExpr.cpp b/lib/MC/MCExpr.cpp index cd4d144..d54c264 100644 --- a/lib/MC/MCExpr.cpp +++ b/lib/MC/MCExpr.cpp @@ -250,6 +250,7 @@ StringRef MCSymbolRefExpr::getVariantKindName(VariantKind Kind) { case VK_Mips_GOT_LO16: return "GOT_LO16"; case VK_Mips_CALL_HI16: return "CALL_HI16"; case VK_Mips_CALL_LO16: return "CALL_LO16"; + case VK_COFF_IMGREL32: return "IMGREL32"; } llvm_unreachable("Invalid variant kind"); } @@ -285,6 +286,8 @@ MCSymbolRefExpr::getVariantKindForName(StringRef Name) { .Case("dtpoff", VK_DTPOFF) .Case("TLVP", VK_TLVP) .Case("tlvp", VK_TLVP) + .Case("IMGREL", VK_COFF_IMGREL32) + .Case("imgrel", VK_COFF_IMGREL32) .Default(VK_Invalid); } -- cgit v1.1
