This release of GNU toolchain and IDE is supported by CGEN IPlib (TCF
generator) version 1.0.53 and later.
New Features and Enhancements
- Toolchain build scripts
- Use GNU FTP server to download GMP, MPFR and MPC, update to latest
versions of those libraries and download .tar.xz files of GMP and MPFR.
- Use GNU FTP server to download GMP, MPFR and MPC, update to latest
- GCC
- Major compiler upgrade from gcc 4.8.5 in previous release to gcc 6.2.1 in this release
- Support for new version of Intel's QuarkSE microcontroller via new mcpu option "quarkse2_em"
- Support -fstack-protector and -fstack-protector-all (uclibc toolchain only)
- Support for profiling using gmon for elf32 toolchain (newlib)
- Remove support for -mabi option. Now GCC always generates function calls
compatible with MetaWare compiler. - Avoid unnecessary dependency of libgcc on newlib.
- Binutils
- Revamped implementation of Position Independent Code (PIC) and Position Independent Executable (PIE)
for much improved and robust support. - Linux security feature: All constant value global symbols which end up as dynamic relocations are now
placed in .data.rel.ro sections and resolved by the dynamic linker and set as read-only.
- Revamped implementation of Position Independent Code (PIC) and Position Independent Executable (PIE)
- GDB
- Support multi-target GDB in ARC code. GDB for baremetal targets now can
debug Linux targets as well.
- Support multi-target GDB in ARC code. GDB for baremetal targets now can
- uClibc
- Migrated to uClibc-ng
- OpenOCD
- Add support for DCCM version 4.
- CGEN
- Removed formal dependency on CGEN repository (no longer in use).
- IDE
- Migrated to use DSF instead of obsolete CDT for debugging, which brings
in multiple usability enhancements. - Updated to latest version of TerminalView plugins.
- Detect if projects has been created with an older version of IDE and show
user a warning that there could be compatibility issues. - Removed support for -mabi option that has been removed from ARC GCC.
- Migrated to use DSF instead of obsolete CDT for debugging, which brings
