  To: buildroot; +Cc: Thomas Petazzoni, ARC Maintainers, Giulio Benetti, Romain Naour

This toolchain is from 2024.06 and has not been updated since then. It
was marked in commit 11a8cdd2bbbd0ef4adf600e4792d75f6f2122ec8 in
January 2025.

A warning was sent to Synopsys ARC people in December 2025, and
despite a reply that some effort would be made [1], no contributions
were actually done. Also, Alexey Brodkin is no longer at
Synopsys. Time to remove Synopsys ARC specific toolchain and toolchain
components.

A warning was sent to Synopsys ARC people in December 2025 that the
ARC support in Buildroot was poorly maintained and in particular the
ARC-pspecific toolchain components. Despite a reply that some effort
would be made [1], no contributions were actually done. Also, Alexey
Brodkin is no longer at Synopsys. Time to remove Synopsys ARC specific
toolchain and toolchain components.

This commit removes the ARC-specific gcc version.

From: Thomas Petazzoni via buildroot @ 2026-08-08 15:27 UTC (permalink / raw)
  To: buildroot; +Cc: Thomas Petazzoni, ARC Maintainers

A warning was sent to Synopsys ARC people in December 2025 that the
ARC support in Buildroot was poorly maintained and in particular the
ARC-pspecific toolchain components. Despite a reply that some effort
would be made [1], no contributions were actually done. Also, Alexey
Brodkin is no longer at Synopsys. Time to remove Synopsys ARC specific
toolchain and toolchain components.

This commit removes the ARC-specific gdb version.

host-flex/host-bison are needed when building GCC from Git or from a
snapshot, not from release tarballs. The condition for the dependency
was actually incorrect: it was needed for the ARC-specific gcc
version (BR2_GCC_VERSION_ARC) but not for the ARC architecture in
general: building upstream GCC release tarballs for ARC does not
require host-flex/host-bison.
