# REQUIRES: mips
[ELF][MIPS] Support R_MIPS_TLS_DTPREL_HI16/LO16 and R_MIPS_TLS_TPREL_HI16/LO16 relocations That is initial and the most trivial patch to support TLS for MIPS targets. llvm-svn: 263712

# Check MIPS R_MIPS_TLS_DTPREL_HI16/LO16 and R_MIPS_TLS_TPREL_HI16/LO16
# relocations handling.

[ELF][MIPS] Improve tests * Add --no-show-raw-insn to llvm-objdump -d tests * When linking an executable with %t.so, the path %t.so will be recorded in the DT_NEEDED entry if %t.so doesn't have DT_SONAME. .dynstr will have varying lengths on different systems. Add -soname to make tests more robust. llvm-svn: 366988

2016-03-17 20:36:08 +08:00
[ELF][MIPS] Treat R_MIPS_TLS_{D}TPREL_HI16/LO16 as relative relocations These relocations are calculated as S + A - DTPREL or S + A - TPREL, where DTPREL = TlsVA - 0x8000, TPREL = TlsVA - 0x7000. So the result is relative to the TLS output section and is not an absolut value The fix allows to escape creation of unnecessary dynamic relocations in case of DSO linking. llvm-svn: 266923
