[ELF] Rename .bss.rel.ro to .data.rel.ro.bss for some Linker Scripts.

LLD uses .bss.rel.ro for read-only copy relocations whereas the ld.bfd and
gold linkers use .data.rel.ro. In some linker scripts including ld.bfd's
internal linker script, the relro sections are placed sequentially assuming
.data.rel.ro is used. LLD's use of .bss.rel.ro means that the copy
relocations get matched into the .bss section causing the relro sections to
be non-contiguous.

This change checks for a .data.rel.ro OutputSection when a linker script
with the SECTIONS command is used. The section will match in the
.data.rel.ro output section and will maintain contiguous relro.

Summary:
This patch aims at condensing the hardware CRC32 feature detection and making
it slightly more effective on Android.

The following changes are included:
- remove the `CPUFeature` enum, and get rid of one level of nesting of
  functions: we only used CRC32, so we just implement and use
  `hasHardwareCRC32`;
- allow for a weak `getauxval`: the Android toolchain is compiled at API level
  14 for Android ARM, meaning no `getauxval` at compile time, yet we will run
  on API level 27+ devices. The `/proc/self/auxv` fallback can work but is
  worthless for a process like `init` where the proc filesystem doesn't exist
  yet. If a weak `getauxval` doesn't exist, then fallback.
- couple of extra corrections.

6 years ago[FindAllSymbols] Cache regexes, creating them is expensive

[FindAllSymbols] Cache regexes, creating them is expensive

This is a bit annoying because LLVM regexes are always mutable to store
errors. Assert that there are never errors and fix broken hardcoded
regexes.

6 years ago[DWARFv5] Support DW_FORM_strp in the .debug_line.dwo header.

[DWARFv5] Support DW_FORM_strp in the .debug_line.dwo header.

As a side effect, the .debug_line section will be dumped in physical
order, rather than in the order that compile units refer to their
associated portions of the .debug_line section.  These are probably
always the same order anyway, and no tests noticed the difference.

6 years ago[OpenMP] Adjust arguments of nvptx runtime functions
Jonas Hahnfeld [Wed, 22 Nov 2017 14:46:49 +0000 (14:46 +0000)]
[OpenMP] Adjust arguments of nvptx runtime functions

In the future the compiler will analyze whether the OpenMP
runtime needs to be (fully) initialized and avoid that overhead
if possible. The functions already take an argument to transfer
that information to the runtime, so pass in the default value 1.
(This is needed for binary compatibility with libomptarget-nvptx
currently being upstreamed.)
