MTK Logo    nanoMIPS GNU toolchain v2021.11-02

        Published on December 03, 2021

Introduction

The nanoMIPS Toolchain includes example code, source code, and documentation to facilitate development of bare metal applications on nanoMIPS simulators and development boards. These toolchains provide compilers, linkers, libraries and utilities for building applications to run on nanoMIPS cores.

Component Description

  • GCC Bare Metal Toolchain
       This is a software engineer's cross-development system for nanoMIPS processors, intended for statically linked embedded applications running on bare metal CPUs or light-weight operating systems.
  • GCC Linux (MUSL) Toolchain
       For compiling Linux applications for Linux running on nanoMIPS cores.

Release Notes

New Features

  • Recognize __builtin_clz on bitwise complemented operand as the CLO instruction [BZ #5].

  • Emit NOT instruction in compiler for bitwise complement operations instead of NOR. Certain NOT instructions can be 16-bit encoded, depending on the register operands [BZ #3].

  • Enable linker relaxation from 32-bit SAVE/RESTORE instructions to 16-bit variants.

Bug Fixes

  • Use JRC.HB instruction instead of just JR for functions with use_hazard_barrier_return attribute [BZ #1].

  • Fix jump-table optimization in GCC to utilize the full 16-bit jump-table range with scaling and prefer unsigned offset tables over signed [BZ #2].

  • Fix internal error in linker when using --emit-relocs with --gc-sections [BZ #7].

  • Fix assembler relaxation to utilize the full range of 16-bit branches [CR MOLY00715449].

  • Fix -fdebug-prefix-map option for LTO builds. Prevent the option from leaking in to gnu.lto_opts and apply its mapping early to byte-code [BZ #9].

  • Updates calls to stat syscall in MUSL to inspect errno in order to detect failures. Raw syscalls that do not modify errno were replaced with syscall wrappers that do in a previous change, however some call sites were not updated to reflect in change in semantics.

  • Fix simulation of SLTI/SLTIU instructions in gdb simulator to not sign-extend immediate operands.

Other Changes

  • Add linker relaxation from 32-bit B[EQ|NE]ZC instructions to 16-bit [BZ #6].

  • Add a multilib variant of libsupc++ built with -fno-exceptions for the link-time command-line option -nortti-libstdc++ [BZ #4].

Known issues

  • The relocation minimization pass in the assembler results in instructions with invalid branch targets in some cases [BZ #17]. This pass is disabled by default and it is advisable to keep it disabled until further notice.

MTK Logo    nanoMIPS GNU toolchain v2021.07-01

        Published on August 06, 2021

Introduction

The nanoMIPS Toolchain includes example code, source code, and documentation to facilitate development of bare metal applications on nanoMIPS simulators and development boards. These toolchains provide compilers, linkers, libraries and utilities for building applications to run on nanoMIPS cores.

Component Description

  • GCC Bare Metal Toolchain
       This is a software engineer's cross-development system for nanoMIPS processors, intended for statically linked embedded applications running on bare metal CPUs or light-weight operating systems.
  • GCC Linux (MUSL) Toolchain
       For compiling Linux applications for Linux running on nanoMIPS cores.

Release Notes

New Features

  • Add variation of memcpy (__aligned_memcpy_no_prefetch) for 4-byte aligned pointers and sizes. This does not perform any validation on alignment of the input parameters. It must be explicitly invoked via a source code change where alignment is known. Behavior will be unpredictable if invoked for misaligned pointers or sizes. It also does not prefetch and is intended for sizes of 128 bytes or less. For larger sizes the standard memcpy is typically faster due to prefetch.

Bug Fixes

  • Fix for incorrect branch targets in assembler output due to minimize relocations pass ( CR MOLY00690538, MOLY00690538).
  • Decouple the minimize relocations pass from jump-table optimization. Previously disabling minimize relocations would inhibit jump-table relaxations and could cause link failures if jump vectors overflow their estimated address range due to linker relaxation. The historic behavior can be restored with the new assembler option -mlegacy-minimize-relocs-behavior.
  • Fix incorrect exception-handling information in assembler due to linker relaxation.
  • Fix internal error in linker due to output sections declared in linker script without any input sections.
  • Fix %a translation for formatted output functions.
  • Fix buffer overrun in formatted output functions.

Other Changes

  • The minimize relocations pass in the assembler is now disabled by default. It can be reenabled by the command-line option -mminimize -relocs.

Known issues

  • None

Release Notes

New Features

  • Add option -flto-preserve-object-names to re-map temporary LTO object names back to original object names at link time. When this option is used, original object names can be matched directly in linker scripts. The linker map file output shows original object names as if generated without LTO.

  • Improve use of 'INS' instruction in situations where bitfield manipulation is expressed in source code using shifts and masks. This should yield improvements in code size and execution speed.

Bug Fixes

  • None.

MTK Logo    nanoMIPS GNU toolchain v2021.02-01

        Published on February 28, 2021

Introduction

The nanoMIPS Toolchain includes example code, source code, and documentation to facilitate development of bare metal applications on nanoMIPS simulators and development boards. These toolchains provide compilers, linkers, libraries and utilities for building applications to run on nanoMIPS cores.

Component Description

  • GCC Bare Metal Toolchain
       This is a software engineer's cross-development system for nanoMIPS processors, intended for statically linked embedded applications running on bare metal CPUs or light-weight operating systems.
  • GCC Linux (MUSL) Toolchain
       For compiling Linux applications for Linux running on nanoMIPS cores.

Release Notes

New Features

  • Add support for the -mfunc-opt-list command-line option to control optimizations on a per-function basis

  • Allow linking against version of libstdc++.a built with -fno-rtti and -fno-exceptions with the link-time command-line option -nortti-libstdc++.

Bug Fixes

  • Fix bad code generation from movep optimization under certain conditions. Option -mno-movep-follow-copy-chains can be used to disable this part of the optimization, if the issue persists.

Other Changes

  • Change newlib's internal _dtoa_r implementation to return a newly malloc'd string, instead
    of reusing a static one. Callers of _dtoa_r are now expected to free the resulting string.
    This enables the printf family of functions to safely format floating-point values in a
    multi-threaded context, but is otherwise transparent to users.

Known issues

  • None

  • None.

Other Changes

  • Rebrand the release from MIPS to MediaTek.

Known issues

  • The movep optimization can lead to bad code generation in some cases. The compiler option -mno-movep-follow-copy-chains can be used to restrict interactions between adjacent optimization sites and avoid this issue.
