Tool/software: TI C/C++ Compiler
Hey, I Use CCS9 with 18.12.2 LTS Compiler.
I'm trying to compile this piece of code with -O2 optimizations.
for (s16_index = 7; s16_index >= 0; s16_index--)
{
s32_temp_vd2[s16_index] = ((long)(s64_temp_vd[s16_index])); // check for numeric overflow
if ((long long)s32_temp_vd2[s16_index] != s64_temp_vd[s16_index])
{
u16_numeric_overflow_flag = 1;
}
}
and i get this error:
>> ../source/BG/Velocity.c, line 3983: INTERNAL ERROR: no match for ASG
This may be a serious problem. Please contact customer support with a
description of this problem and a sample of the source files that caused this
INTERNAL ERROR message to appear.
Cannot continue compilation - ABORTING!
gmake: *** [Velocity.obj] Error 1
from spru514p:
--opt_level=2 or -O2
Performs all --opt_level=1 (-O1) optimizations, plus:
– Performs loop optimizations
– Eliminates global common subexpressions
– Eliminates global unused assignments
– Performs loop unrolling
So i change the for loop to:
for (s16_index = 0; s16_index < 8; ++s16_index)
{
s32_temp_vd2[s16_index] = ((long)(s64_temp_vd[s16_index])); // check for numeric overflow
if ((long long)s32_temp_vd2[s16_index] != s64_temp_vd[s16_index])
{
u16_numeric_overflow_flag = 1;
}
}
And it compiles well.
With optimizations less than -O2 both variants compile well.
Please shine some light on this issue.
My compiler flags:
-v28 -ml -mt --float_support=fpu32 -O2 --opt_for_speed=2 --advice:performance=all --define="_DEBUG" --define="LARGE_MODEL" --symdebug:none --diag_error=225 --diag_error=2082 --display_error_number --issue_remarks --quiet --abi=coffabi -k --asm_listing --c_src_interlist --asm_directory="${CWD}" --obj_directory="${CWD}"
