* [mc] Fix ELF st_other flag.Logan Chien2013-12-05
| | | | | | | | | | | | | ELF_Other_Weakref and ELF_Other_ThumbFunc seems to be LLVM internal ELF symbol flags. These should not be emitted to object file. This commit defines ELF_STO_Shift for the target-defined flags for st_other, and increase the value of ELF_Other_Shift to 16. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196440 91177308-0d34-0410-b5e6-96231b3b80d8
* Move the STT_FILE symbols out of the normal symbol table processing forJoerg Sonnenberger2013-10-29
| | | | | | | | ELF. They can overlap with the other symbols, e.g. if a source file "foo.c" contains a function "foo" with a static variable "c". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193569 91177308-0d34-0410-b5e6-96231b3b80d8
* ELF symbol table field st_other support, Jack Carter2013-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | excluding visibility bits. Generic STO handling at the Target level. The st_other field of the ELF symbol table is one byte in size. The first 2 bytes are used for generic visibility and are currently handled by llvm. The other six bits are processor specific and need to be set at the target level. A couple of notes: The new static methods for accessing and setting the "other" flags in include/llvm/MC/MCELF.h match the style guide and not the other methods in the file. I don't like the inconsistency, but feel I should follow the prescribed lowerUpper() convention. STO_ value definitions are not specified in gnu land as consistently as the STT_ and STB_ fields. Probably because the latter were defined in a standards doc and the former defined partially in code. I have stuck with the full byte definition of the flags.

* Added Mapping Symbols for ARM ELFTim Northover2012-12-07
| | | | | | | | | | Before this patch, when you objdump an LLVM-compiled file, objdump tried to decode data-in-code sections as if they were code. This patch adds the missing Mapping Symbols, as defined by "ELF for the ARM Architecture" (ARM IHI 0044D). Patch based on work by Greg Fitzgerald. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169609 91177308-0d34-0410-b5e6-96231b3b80d8
