Merge commit da7b129b1 from llvm git (by James Clarke):

[RISCV] Don't force Local Exec TLS for non-PIC

Summary:

Forcing Local Exec TLS requires the use of copy relocations. Copy
relocations need special handling in the runtime linker when being
used against TLS symbols, which is present in glibc, but not in
FreeBSD nor musl, and so cannot be relied upon. Moreover, copy
relocations are a hack that embed the size of an object in the ABI
when it otherwise wouldn't be, and break protected symbols (which are
expected to be DSO local), whilst also wasting space, thus they
should be avoided whenever possible. As discussed in D70398, RISC-V
should move away from forcing Local Exec, and instead use Initial
Exec like other targets, with possible linker relaxation to follow.
The RISC-V GCC maintainers also intend to adopt this
more-conventional behaviour (see
https://github.com/riscv/riscv-elf-psabi-doc/issues/122).

Move all sources from the llvm project into contrib/llvm-project.

This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo". That is, most of
the earlier separate sub-projects with their own branches and tags were
consolidated into one top-level directory, and are now branched and
tagged together.

Updating the vendor area to match this layout is next.

relocations need special handling in the runtime linker when being
used against TLS symbols, which is present in glibc, but not in
FreeBSD nor musl, and so cannot be relied upon. Moreover, copy
relocations are a hack that embed the size of an object in the ABI
when it otherwise wouldn't be, and break protected symbols (which are
expected to be DSO local), whilst also wasting space, thus they
should be avoided whenever possible. As discussed in D70398, RISC-V
should move away from forcing Local Exec, and instead use Initial
Exec like other targets, with possible linker relaxation to follow.
The RISC-V GCC maintainers also intend to adopt this
more-conventional behaviour (see

Move all sources from the llvm project into contrib/llvm-project.

This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo". That is, most of
the earlier separate sub-projects with their own branches and tags were
consolidated into one top-level directory, and are now branched and
tagged together.

Updating the vendor area to match this layout is next.

[RISCV] Don't force Local Exec TLS for non-PIC

Summary:

Forcing Local Exec TLS requires the use of copy relocations. Copy
relocations need special handling in the runtime linker when being
used against TLS symbols, which is present in glibc, but not in
FreeBSD nor musl, and so cannot be relied upon. Moreover, copy
relocations are a hack that embed the size of an object in the ABI
when it otherwise wouldn't be, and break protected symbols (which are
expected to be DSO local), whilst also wasting space, thus they
should be avoided whenever possible. As discussed in D70398, RISC-V
should move away from forcing Local Exec, and instead use Initial
Exec like other targets, with possible linker relaxation to follow.
The RISC-V GCC maintainers also intend to adopt this
more-conventional behaviour (see
https://github.com/riscv/riscv-elf-psabi-doc/issues/122).

Move all sources from the llvm project into contrib/llvm-project.

This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo". That is, most of
the earlier separate sub-projects with their own branches and tags were
consolidated into one top-level directory, and are now branched and
tagged together.

Updating the vendor area to match this layout is next.

FreeBSD nor musl, and so cannot be relied upon. Moreover, copy
relocations are a hack that embed the size of an object in the ABI
when it otherwise wouldn't be, and break protected symbols (which are
expected to be DSO local), whilst also wasting space, thus they
should be avoided whenever possible. As discussed in D70398, RISC-V
should move away from forcing Local Exec, and instead use Initial
Exec like other targets, with possible linker relaxation to follow.
The RISC-V GCC maintainers also intend to adopt this
more-conventional behaviour (see
https://github.com/riscv/riscv-elf-psabi-doc/issues/122).

Move all sources from the llvm project into contrib/llvm-project.

This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo". That is, most of
the earlier separate sub-projects with their own branches and tags were
consolidated into one top-level directory, and are now branched and
tagged together.

Updating the vendor area to match this layout is next.

Merge commit 7214f7a79 from llvm git (by Sam Elliott):

[RISCV] Lower llvm.trap and llvm.debugtrap

Summary:
Until this commit, these have lowered to a call to abort().

`llvm.trap()` now lowers to `unimp`, which should trap on all systems.

`llvm.debugtrap()` now lowers to `ebreak`, which is exactly what this
instruction is for.

Merge commit da7b129b1 from llvm git (by James Clarke):

[RISCV] Don't force Local Exec TLS for non-PIC

Summary:

Forcing Local Exec TLS requires the use of copy relocations. Copy
relocations need special handling in the runtime linker when being
used against TLS symbols, which is present in glibc, but not in
FreeBSD nor musl, and so cannot be relied upon. Moreover, copy
relocations are a hack that embed the size of an object in the ABI
when it otherwise wouldn't be, and break protected symbols (which are
expected to be DSO local), whilst also wasting space, thus they
should be avoided whenever possible. As discussed in D70398, RISC-V
should move away from forcing Local Exec, and instead use Initial
Exec like other targets, with possible linker relaxation to follow.
