NVHPC 21.9 produces "Internal compiler error. Unhandled builtin function." when sin() is used in the mod file #677
Description
Describe the issue
If mod uses math intrinsic function sin() then NVHPC v21.9 produces following error:
Translating x86_64/corenrn/mod2c/kcaPR.mod into x86_64/corenrn/mod2c//kcaPR.cpp
cvode_emit=0 cvode_not_allowed=0
Thread Safe
Unhandled builtin: 47 (sin)
NVC++-F-0000-Internal compiler error. Unhandled builtin function. 0 (x86_64/corenrn/mod2c/kcaPR.cpp: 489)
NVC++/x86-64 Linux 21.9-0: compilation aborted
make: *** [x86_64/corenrn/build/kcaPR.o] Error 2Previous version installed on BB5 works fine.
To Reproduce
Install latest master of coreneuron+mod2c with NVHPC 21.9 and compile mod file containing call to sin():
mkdir -p test && cd test
wget https://raw.githubusercontent.com/soltesz-lab/dentate/92e8d95b9b200669804dda05dfdc49696943f369/mechanisms/PinskyRinzel/kcaPR.mod

=> Binary creating x86_64/special-coreExpected behavior
MOD files should be built fine and executable should be created
System (please complete the following information)
- System: BB5
- Compiler: NVHPC 21.9
- Version: master
- Backend: GPU backend with GPU
Additional context
Didn't look into details but if I avoid accelmath.h include then it builds fine:
#if defined(__PGI)
#include "accelmath.h"
#endif

Also, I only reproduced the error with MOD2C (not NMODL).
