Command line tools

Hi all,-

I guess I have a lot of topics on my mind. But to get started ... :

Windows 10, command line tools 3.1... 

Running hexagon-sim <executable> works just fine eg. for the example bkfir found in:

C:\Qualcomm\Hexagon_SDK\3.1\tools\HEXAGON_Tools\8.0.08\Examples\c_optimization\bkfir

Note: I had to edit the setup_sdk_env.cmd file in C:\Qualcomm\Hexagon_SDK\3.1\ to include the PATH for the tools in order to run the MAKE.

Q1: Is there a way to run the simulator to singlestep through code? at C or ASM level??? and see registers, variables, memory etc.?

Q2: The example bkfir is quite fine in respect of showing some aspects of a FIR filter and illustrates the power of intrinsics - But wouldn't it be a natural intermediate step to look more closely at the assembly STAGE of the compiler. I can manage to get to that by doing a bit of

"hexagon-llvm-objdump  -disassemble bkfir.o"
Thereby getting almost the assembly code of whatever C version of the bkfir.c...
But I haven't found the option / switch / command for the compiler to emit that assembly code to me (with symbolic names for addresses)

Anybody with ideas on these topics?

Br,

Henrik

Ahhh - 

Related to my own Q1... 

hexagon-sim -interactive <exe-file> is the option to use to be able to single step... or run a number of cycles.

SHOWREGS toggle show of the registers on/off - STEP executes instruction packets

Dump show memory content

Nothing fancy - and only disassembly of the present instruction - no higher level / symbolic stuff.
