[ELF][MIPS] MIPS .reginfo sections handling MIPS .reginfo section provides information on the registers used by the code in the object file. Linker should collect this information and write .reginfo section in the output file. This section contains a union of used registers masks taken from input .reginfo sections and final value of the `_gp` symbol. For details see the "Register Information" section in Chapter 4 in the following document: ftp://www.linux-mips.org/pub/linux/mips/doc/ABI/mipsabi.pdf The patch implements .reginfo sections handling with a couple missed features: a) it does not put output .reginfo section into the separate REGINFO segment; b) it does not merge `ri_cprmask` masks from input section. These features will be implemented later. Differential Revision: http://reviews.llvm.org/D15669 llvm-svn: 256119

ELF: Improve performance of string table construction. String tables in unstripped executable files are fairly large in size. For example, lld's executable file is about 34.4 MB in my environment, and of which 3.5 MB is the string table. Efficiency of string table construction matters. Previously, the string table was built in an inefficient way. We used StringTableBuilder to build that and enabled string tail merging, although tail merging is not effective for the symbol table (you can only make the string table 0.3% smaller for lld.) Tail merging is computation intensive task and slow. This patch eliminates string tail merging. I changed the way of adding strings to the string table in this patch too. Previously, strings were added using add() and the same strings were then passed to getOffset() to get their offsets in the string table. In this way, getOffset() needs to look up a hash table to get offsets for given strings. This is a violation of "we look up the symbol table (or a hash table) only once for each symbol" dogma of the new LLD's design. Hash table lookup for long C++ mangled names is slow. I eliminated that lookup in this patch. In total, this patch improves link time of lld itself about 12% (3.50 seconds -> 3.08 seconds.) llvm-svn: 257017

ELF2: Write .interp section on the first page in the exectuable. Previously, we reserved the first page for the program header, so no sections would be written to very beginning of the output file. FreeBSD requires .interp section be exist on the first page, so that was not good. This patch calculates the size of the program header and then assign addresses to the sections. Now the first section is located next to the program header. Because the first section is .interp, it's very likely to be on the first page. llvm-svn: 249957

Handle 0 sized sections like any other section. This is a case where there is inconsistency among ELF linkers: * The spec says nothing special about empty sections. * BFD ld removes them. * Gold handles them like regular sections. We were outputting them but sometimes ignoring them. This would create odd looking outputs where a rw section could be in a ro segment for example. The bfd way of doing things is also strange for the case where a symbol points to the empty section. Now we match gold and what seems to be the intention of the spec. llvm-svn: 251988

For the detailed description about GOT in MIPS, see "Global Offset Table" in Chapter 5 in the followin document: ftp://www.linux-mips.org/pub/linux/mips/doc/ABI/mipsabi.pdf In addition, the platform specific symbol "_gp" is added, see "Global Data Symbols" in Chapter 6 in the aforementioned document.

ELF2: Write .interp section on the first page in the exectuable. Previously, we reserved the first page for the program header, so no sections would be written to very beginning of the output file. FreeBSD requires .interp section be exist on the first page, so that was not good. This patch calculates the size of the program header and then assign addresses to the sections. Now the first section is located next to the program header. Because the first section is .interp, it's very likely to be on the first page. llvm-svn: 249957

Handle 0 sized sections like any other section. This is a case where there is inconsistency among ELF linkers: * The spec says nothing special about empty sections. * BFD ld removes them. * Gold handles them like regular sections. We were outputting them but sometimes ignoring them. This would create odd looking outputs where a rw section could be in a ro segment for example. The bfd way of doing things is also strange for the case where a symbol points to the empty section. Now we match gold and what seems to be the intention of the spec. llvm-svn: 251988
