[RISCV] Integrate RISCV target in baremetal toolchain object and deprecate RISCVToolchain object #121831

quic-garvgupt · 2025-01-06T20:25:00Z

This patch:

Adds CXXStdlib, runtimelib and unwindlib defaults for riscv target to
BareMetal toolchain object.
Add riscv 32 and 64-bit emulation flags to linker job of BareMetal
toolchain.
Removes call to RISCVToolChain object from llvm.

This PR is last patch in the series of patches of merging RISCVToolchain
object into BareMetal toolchain object.

RISCVToolchain object.(3/3)

This PR is last in the series of merging RISCVToolchain object into BareMetal
toolchain object.

The division of the PRs is as follows:

Teach Baremetal toolchain about GCC installation and make sysroot and
assembler
related changes.
Changes related to linker job and defaults for CXXStdlib and other runtime
libs.
Finally removing the call to RISCVToolchain object.

Changes

RISCVToolchain object.(3/3)

This PR is last in the series of merging RISCVToolchain object into BareMetal
toolchain object.

The division of the PRs is as follows:

Teach Baremetal toolchain about GCC installation and make sysroot and
assembler
related changes.
Changes related to linker job and defaults for CXXStdlib and other runtime
libs.
Finally removing the call to RISCVToolchain object.

RFC:
https://discourse.llvm.org/t/merging-riscvtoolchain-and-baremetal-toolchains/75524

Hi @petrhosek , I understand you had some feedback regarding further splitting this PR however I responded to all of them. If you do not have any further comments/feedback, will really appreciate if you can approve this PR. Thanks again for reviewing all the patches!

…ecate RISCVToolchain object This patch: - Adds CXXStdlib, runtimelib and unwindlib defaults for riscv target to BareMetal toolchain object. - Add riscv 32 and 64-bit emulation flags to linker job of BareMetal toolchain. - Removes call to RISCVToolChain object from llvm. This PR is last patch in the series of patches of merging RISCVToolchain object into BareMetal toolchain object. RFC: https: //discourse.llvm.org/t/merging-riscvtoolchain-and-baremetal-toolchains/75524 Change-Id: Ic5d64a4ed3ebc58c30c12d9827e7e57a02eb13ca
