2012-08-22For mips64 switch statements in subroutines could generate Jack Carter
within the codegen EK_GPRel64BlockAddress. This was not supported for direct object output and resulted in an assertion. This change adds support for EK_GPRel64BlockAddress for direct object. One fallout from this is to turn on rela relocations for mips64 to match gas. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162334 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-08Add `.pushsection', `.popsection', and `.previous' directives to Darwin ASM.Bill Wendling
There are situations where inline ASM may want to change the section -- for instance, to create a variable in the .data section. However, it cannot do this without (potentially) restoring to the wrong section. E.g.: asm volatile (".section __DATA, __data\n\t" ".globl _fnord\n\t" "_fnord: .quad 1f\n\t" ".text\n\t" "1:" :::); This may be wrong if this is inlined into a function that has a "section" attribute. The user should use `.pushsection' and `.popsection' here instead. The addition of `.previous' is added for completeness. <rdar://problem/12048387> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161477 91177308-0d34-0410-b5e6-96231b3b80d8

Empty macro arguments at the end of the list should be as-if not specified at all, but those in the middle of the list need to be kept so as not to screw up the positional numbering. E.g.: .macro foo foo_-bash___: nop .endm foo 1, 2, 3, 4 foo 1, , 3, 4 Should create two labels, "foo_1_2_3_4" and "foo_1__3_4". rdar://11948769 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161002 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-07I'm introducing a new machine model to simultaneously allow simpleAndrew Trick
subtarget CPU descriptions and support new features of MachineScheduler. MachineModel has three categories of data: 1) Basic properties for coarse grained instruction cost model. 2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD). 3) Instruction itineraties for detailed per-cycle reservation tables. These will all live side-by-side. Any subtarget can use any combination of them. Instruction itineraries will not change in the near term. In the long run, I expect them to only be relevant for in-order VLIW machines that have complex contraints and require a precise scheduling/bundling model. Once itineraries are only actively used by VLIW-ish targets, they could be replaced by something more appropriate for those targets. This tablegen backend rewrite sets things up for introducing MachineModel type #2: per opcode/operand cost model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159891 91177308-0d34-0410-b5e6-96231b3b80d8

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

Use a dedicated MachO load command to annotate data-in-code regions. This is the same format the linker produces for final executable images, allowing consistency of representation and use of introspection tools for both object and executable files. Data-in-code regions are annotated via ".data_region"/".end_data_region" directive pairs, with an optional region type. data_region_directive := ".data_region" { region_type } region_type := "jt8" | "jt16" | "jt32" | "jta32" end_data_region_directive := ".end_data_region" The previous handling of ARM-style "$d.*" labels was broken and has been removed.
