Toolchain path to Keil C51. The location of the toolchain is automatically set to c: keil. Studio does not yet support multiple Keil or GCC. Keil 4安装过程中出现 *** tools.ini: toolchain not installed ***错误，不知道如何解决，好心人帮帮忙吧 我来答.

The integrated assembler now reports error: invalid symbol redefinition. • [SDCOMP-47603] The inline assembler and integrated assembler would incorrectly accept invalid special register masks for the MSR instruction, and then generate an instruction with all of the mask bits set. This has been fixed. The inline assembler and integrated assembler now report error: invalid operand for instruction.

This has been fixed. The compiler now reports error: use of undeclared identifier '. • [SDCOMP-48003] In certain circumstances, the compiler could incorrectly translate calls to wide character variants of the scanf() family of library functions, or non-wide character variants called with a wide character format specifier, into calls to versions of these functions provided by the ARM C library that do not have the required wide character support. This has been fixed. • [SDCOMP-47948] When compiling with -mexecute-only, the compiler incorrectly failed to report an error when the program was compiled for A32 state or with hardware floating-point usage enabled. This has been fixed. The compiler now reports one of the following: • error: execute only is not supported for ARM mode execution • error: execute only is not supported when generating floating-point instructions • [SDCOMP-47867] When compiling with -ftrapv for an ARMv6-M target or an ARMv8-M target without the Main Extension, the compiler would generate incorrect code that trapped all signed multiplication operations which have one positive operand and one negative operand.

• ARM Compiler 6 includes the libc++ library as the C++ Standard Template Library. Note regarding assemblers: • ARM Compiler 6 adopts the LLVM integrated assembler as default because it aligns more closely with GNU assembler syntax, improving portability between GNU and ARM Compiler toolchains.

• The legacy assembler ( armasm) is not called by default, but is included in Arm Compiler 6 for assembling source code written in armasm syntax. The legacy assembler is included to help with migration of existing projects from Arm Compiler 5 or earlier. Although the legacy assembler has been extended to support Armv8, this assembler does not include all the features of the latest Armv8 updates, and Arm has no plans to add further architectural support to armasm. For new projects, Arm recommends the armclang inline assembler and integrated assembler.

User experimentation and feedback is welcomed. Alpha product features Implementation is not complete and not thoroughly tested.

This has been fixed. Known issues in ARM Compiler 6.8 • [SDCOMP-47864] Link time optimization (LTO) is not supported when compiling with -march= name+sve for a target that supports the Scalable Vector Extension (SVE). To avoid the use of LTO: • Do not compile with -flto option and do not link with --lto. Telecharger nos jours heureux dvdrip uptobox search. • When compiling at -Omax, also compile with -fno-lto and link with --no_lto.

• [SDCOMP-26080] Complex numbers are not supported. Release notes for ARM Compiler 6.5 1. Introduction ARM Compiler 6.5 adds: • Support for Cortex-A73. The compiler also includes a number of optimizations that result in better performance of the generated code over the previous release, and some improvements in code size.

Support Level Description Product features Production quality. Highest support priority. 2000 polaris xpedition 425 service manual. Beta product features Implementation complete, but not thoroughly tested.

• [SDCOMP-48900] The inline assembler and integrated assembler would incorrectly treat an invalid use of the # character as the start of a comment. This could result in the assembler incorrectly treating an invalid instruction as a different but valid instruction. This has been fixed. The inline assembler and integrated assembler now report error: unexpected token in argument list. • [SDCOMP-48825] In rare circumstances, when compiling for AArch32 state, and the code contains a comparison operation, the compiler could generate incorrect code that corrupts the Application Program Status Register (APSR). This has been fixed. • [SDCOMP-48772] When assembling for AArch32 state for a target that supports the optional Dot Product instructions, the inline assembler and integrated assembler incorrectly failed to report an error for a VUDOT instruction that specifies an invalid register name for the second source register operand.
