Important Notices

This patch contains changes to the following components:

• TriCore C++ compiler
• TriCore C compiler
• TriCore assembler
• TriCore control program (for C++ compiler invocations)
• The stdbool.h header file (when used in C++ code)
• TriCore libc++ header files
• TriCore STLport C++ header files
• SFR files for AURIX 2G

Please note that the TriCore libraries have been rebuilt. These libraries are also part of this patch.

This patch adds the following components:

• Files to provide compiler support for TC35x, TC36x and TC37x AURIX devices
  Note that when you change the device of an existing example to one of the newly supported devices, the start up files and sync_on_halt must be re-imported. For the tc_blink_aurix example this is not required.


• Files to provide debugger support for the following AURIX hardware:
  • TC357 on a TC3x7 TriBoard
  • TC377 on a TC3x7 TriBoard
    Note that a DAS driver version higher than v7.0.6 is required to support the TC377 device.
  • TC387 on a TC3x7 TriBoard

Please note that this patch does not add Pin Mapper support for TC35x, TC36x and TC37x. Support for these devices is provided by means of the stand-alone version of the Pin Mapper.

Fixed Issues in v6.2r2p4

Fixed Problems

• TCVX-43868 - Run-time error for double _Complex expression passing to a function
• TCVX-43893 - C compiler optimizes user stack incorrectly
• TCVX-43915 - Unroll small loops optimization leads to wrong code when speed tradeoff -t0 used

• TCVX-43931 - EMEM memory definition missing in TC35x LSL file

New Device Support

Fixed Issues in v6.2r2p3

Fixed Problems

• TCVX-43517 - Math functions log10f() and log2f() use double precision arithmetic
• TCVX-43696 - Reading elements of a const aggregate object as a larger type may result in an incorrect value
• TCVX-43704 - Non justified if condition optimization
