Fix two issues: 1. The script assumes the default CMake generator build tool platform is installed. On Linux at least, that's Make instead of Ninja, but Make might not be installed since Zephyr recommends Ninja. On Windows, that might be VS Code or nmake. Calling `cmake -P pristine` instead of `cmake --build <path> --target pristine` has the benefit of removing the dependency on a build command, and hence the default generator is not relevant. 2. It also assumes run_cmake() returns control, and therefore pristine can be run. However, if the cmake command fails hard (say, due to issue #1 before this patch), run_cmake() throws an exception instead. Fix that by trying to run the pristine target in a finally block instead, and adding some manual cleanup steps in case the build system is in a bad state and pristine fails too.

This makes the gatt metrics also available for gatt write-without-rsp-cb so it now prints the rate of each write: uart:~$ gatt write-without-response-cb 1e ff 10 10 Write #1: 16 bytes (0 bps) Write zephyrproject-rtos#2: 32 bytes (3445948416 bps) Write zephyrproject-rtos#3: 48 bytes (2596929536 bps) Write zephyrproject-rtos#4: 64 bytes (6400 bps) Write zephyrproject-rtos#5: 80 bytes (8533 bps) Write zephyrproject-rtos#6: 96 bytes (10666 bps) Write zephyrproject-rtos#7: 112 bytes (8533 bps) Write zephyrproject-rtos#8: 128 bytes (9955 bps) Write zephyrproject-rtos#9: 144 bytes (11377 bps) Write zephyrproject-rtos#10: 160 bytes (7680 bps) Write zephyrproject-rtos#11: 176 bytes (8533 bps) Write zephyrproject-rtos#12: 192 bytes (9386 bps) Write Complete (err 0) Write zephyrproject-rtos#13: 208 bytes (8533 bps) Write zephyrproject-rtos#14: 224 bytes (9244 bps) Write zephyrproject-rtos#15: 240 bytes (9955 bps) Write zephyrproject-rtos#16: 256 bytes (8000 bps) Signed-off-by: Luiz Augusto von Dentz <[email protected]>

The _ldiv5() is an optimized divide-by-5 function that is smaller and
faster than the generic libgcc implementation.
Yet it can be made even smaller and faster with this replacement
implementation based on a reciprocal multiplication plus some tricks.
For example, here's the assembly from the original code on ARM:
_ldiv5:
ldr r3, [r0]
movw ip, zephyrproject-rtos#52429
ldr r1, [r0, zephyrproject-rtos#4]
movt ip, 52428
adds r3, r3, zephyrproject-rtos#2
push {r4, r5, r6, r7, lr}
mov lr, #0
adc r1, r1, lr
adds r2, lr, lr
umull r7, r6, ip, r1
lsr r6, r6, zephyrproject-rtos#2
adc r7, r6, r6
adds r2, r2, r2
adc r7, r7, r7
adds r2, r2, lr
adc r7, r7, r6
subs r3, r3, r2
sbc r7, r1, r7
lsr r2, r3, zephyrproject-rtos#3
orr r2, r2, r7, lsl zephyrproject-rtos#29
umull r2, r1, ip, r2
lsr r2, r1, zephyrproject-rtos#2
lsr r7, r1, zephyrproject-rtos#31
lsl r1, r2, zephyrproject-rtos#3
adds r4, lr, r1
adc r5, r6, r7
adds r2, r1, r1
adds r2, r2, r2
adds r2, r2, r1
subs r2, r3, r2
umull r3, r2, ip, r2
lsr r2, r2, zephyrproject-rtos#2
adds r4, r4, r2
adc r5, r5, #0
strd r4, [r0]
pop {r4, r5, r6, r7, pc}
And here's the resulting assembly with this commit applied:
_ldiv5:
push {r4, r5, r6, r7}
movw r4, zephyrproject-rtos#13107
ldr r6, [r0]
movt r4, 13107
ldr r1, [r0, zephyrproject-rtos#4]
mov r3, #0
umull r6, r7, r6, r4
add r2, r4, r4, lsl #1
umull r4, r5, r1, r4
adds r1, r6, r2
adc r2, r7, r2
adds ip, r6, r4
adc r1, r7, r5
adds r2, ip, r2
adc r2, r1, r3
adds r2, r4, r2
adc r3, r5, r3
strd r2, [r0]
pop {r4, r5, r6, r7}
bx lr
So we're down to 20 instructions from 36 initially, with only 2 umull
instructions instead of 3, and slightly smaller stack footprint.

The fatal log now contains - Trap type in human readable representation - Integer registers visible to the program when trap was taken - Special register values such as PC and PSR - Backtrace with PC and SP If CONFIG_EXTRA_EXCEPTION_INFO is enabled, then all the above is logged. If not, only the special registers are logged. The format is inspired by the GRMON debug monitor and TSIM simulator. A quick guide on how to use the values is in fatal.c. It now looks like this: E: tt = 0x02, illegal_instruction E: E: INS LOCALS OUTS GLOBALS E: 0: 00000000 f3900fc0 40007c50 00000000 E: 1: 00000000 40004bf0 40008d30 40008c00 E: 2: 00000000 40004bf4 40008000 00000003 E: 3: 40009158 00000000 40009000 00000002 E: 4: 40008fa8 40003c00 40008fa8 00000008 E: 5: 40009000 f3400fc0 00000000 00000080 E: 6: 4000a1f8 40000050 4000a190 00000000 E: 7: 40002308 00000000 40001fb8 000000c1 E: E: psr: f30000c7 wim: 00000008 tbr: 40000020 y: 00000000 E: pc: 4000a1f4 npc: 4000a1f8 E: E: pc sp E: #0 4000a1f4 4000a190 E: #1 40002308 4000a1f8 E: zephyrproject-rtos#2 40003b24 4000a258 Signed-off-by: Martin Åberg <[email protected]>
