Compiler/RM46L852: CMSIS_5 - build arm_sqrt_qXX.c - Undefined symbol SUB

Part Number: RM46L852

Tool/software: TI C/C++ Compiler

I try to compile the CMSIS DSP lib for RM46L852. I use the CMSIS-5.1.1 version and the CCS-7.3.

The build exit with 2 errors :

"D:\\ti\\ccsv7\\utils\\bin\\gmake" -k -j 4 CMSIS/DSP/Source/FastMathFunctions/arm_sqrt_q15.obj -O

'Building file: ../CMSIS/DSP/Source/FastMathFunctions/arm_sqrt_q15.c'

gmake: *** [CMSIS/DSP/Source/FastMathFunctions/arm_sqrt_q15.obj] Error 1

Same error on file ../CMSIS/DSP/Source/FastMathFunctions/arm_sqrt_q31.c

More informations:

  •  The error disapear when the following line of arm_sqrt_q15.c is disabled.
    /*Store as integer */
    tempconv.floatval = temp_float1;
  • or The error disapear when the optimisation of the file is decreased to 0. In all other case of optimisation level, the build exit with error.

I have selected RM46L852 device and the SUB instruction exist on this armv7 processor. Compiler bug ?
Or a problem on the predefined symbol --define=ARM_MATH_CM4 --define=__TI_ARM_V7M4__  ?

    This appears to be a bug in the compiler.  I'd appreciate if, for the file arm_sqrt_q15.c, you would send in a test case as described in the article How to Submit a Compiler Test Case.

    Thanks and regards,

    -George

    I agree, I think the compiler is generating a bogus instruction.

    Thank you for submitting a test case.  I can reproduce the problem.  I filed CODEGEN-3880 in the SDOWP system to have this investigated.  You are welcome to follow it with the SDOWP link below in my signature.

    Thanks and regards,

    -George
