2012-06-28Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp andBill Wendling

2012-06-27The ELF relocation record format is different for N64 Jack Carter
which many Mips 64 ABIs use than for O64 which many if not all other target ABIs use. Most architectures have the following 64 bit relocation record format: typedef struct { Elf64_Addr r_offset; /* Address of reference */ Elf64_Xword r_info; /* Symbol index and type of relocation */ } Elf64_Rel; typedef struct { Elf64_Addr r_offset; Elf64_Xword r_info; Elf64_Sxword r_addend; } Elf64_Rela; Whereas N64 has the following format: typedef struct { Elf64_Addr r_offset;/* Address of reference */ Elf64_Word r_sym; /* Symbol index */ Elf64_Byte r_ssym; /* Special symbol */ Elf64_Byte r_type3; /* Relocation type */ Elf64_Byte r_type2; /* Relocation type */ Elf64_Byte r_type; /* Relocation type */ } Elf64_Rel; typedef struct { Elf64_Addr r_offset;/* Address of reference */ Elf64_Word r_sym; /* Symbol index */ Elf64_Byte r_ssym; /* Special symbol */ Elf64_Byte r_type3; /* Relocation type */ Elf64_Byte r_type2; /* Relocation type */ Elf64_Byte r_type; /* Relocation type */ Elf64_Sxword r_addend; } Elf64_Rela; The structure is the same size, but the r_info data element is now 5 separate elements. Besides the content aspects, endian byte reordering will be different for the area with each element being endianized separately. I treat this as generic and continue to pass r_type as an integer masking and unmasking the byte sized N64 values for N64 mode. I've implemented this and it causes no affect on other current targets. This passes make check. Jack git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159299 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-21The inline asm operand modifier 'c' is suppose Jack Carter
to be generic across architectures. It has the following description in the gnu sources: Substitute immediate value without immediate syntax Several Architectures such as x86 have local implementations of operand modifier 'c' which go beyond the above description slightly. To make use of the generic modifiers without overriding local implementation one can make a call to the base class method for AsmPrinter::PrintAsmOperand() in the locally derived method's "default" case in the switch statement. That way if it is already defined locally the generic version will never get called. This change is needed when test/CodeGen/generic/asm-large-immediate.ll failed on a native Mips board. The test was assuming a generic implementation was in place. Affected files: lib/Target/Mips/MipsAsmPrinter.cpp: Changed the default case to call the base method. lib/CodeGen/AsmPrinter/AsmPrinterInlineAsm.cpp Added 'c' to the switch cases. test/CodeGen/Mips/asm-large-immediate.ll Mips compiled version of the generic one Contributer: Jack Carter git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158925 91177308-0d34-0410-b5e6-96231b3b80d8
