* Various fixes to how timer differences are calculated (#8585)Purdea Andrei2020-04-111-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * tmk_core/common: Fixing TIMER_DIFF macro to calculate difference correctly after the timer wraps. Let's go through an example, using the following macro: If the first timer read is 0xe4 and the second one is 0x32, the timer wrapped. If the timer would have had more bits, it's new value would have been 0x132, and the correct difference in time is 0x132 - 0xe4 = 0x4e old code TIMER_DIFF_8(0x32, 0xe4) = 0xff - 0xe4 + 0x32 = 0x4d, which is wrong. new code TIMER_DIFF_8(0x32, 0xe4) = 0xff + 1 - 0xe4 + 0x32 = 0x4e, which is correct. This also gives a chance for a smart compiler to optimize the code using normal integer overflow. For example on AVR, the following C code: uint8_t __attribute__ ((noinline)) test(uint8_t current_timer, uint8_t start_timer) { return TIMER_DIFF_8(current_timer, start_timer); } With the original code, it gets translated to the following list of instructions: 00004c6e <test>: 4c6e: 98 2f mov r25, r24 4c70: 86 1b sub r24, r22 4c72: 96 17 cp r25, r22 4c74: 08 f4 brcc .+2 ; 0x4c78 <test+0xa> 4c76: 81 50 subi r24, 0x01 ; 1 4c78: 08 95 ret But with this commit, it gets translated to a single instruction: 00004c40 <test>: 4c40: 86 1b sub r24, r22 4c42: 08 95 ret This unfortunately doesn't always work so nicely, for example the following C code: int __attribute__ ((noinline)) test(uint8_t current_timer, uint8_t start_timer) { return TIMER_DIFF_8(current_timer, start_timer); } (Note: return type changed to int) With the original code it gets translated to: 00004c6e <test>: 4c6e: 28 2f mov r18, r24 4c70: 30 e0 ldi r19, 0x00 ; 0 4c72: 46 2f mov r20, r22 4c74: 50 e0 ldi r21, 0x00 ; 0 4c76: 86 17 cp r24, r22 4c78: 20 f0 brcs .+8 ; 0x4c82 <test+0x14> 4c7a: c9 01 movw r24, r18 4c7c: 84 1b sub r24, r20 4c7e: 95 0b sbc r25, r21 4c80: 08 95 ret 4c82: c9 01 movw r24, r18 4c84: 84 1b sub r24, r20 4c86: 95 0b sbc r25, r21 4c88: 81 50 subi r24, 0x01 ; 1 4c8a: 9f 4f sbci r25, 0xFF ; 255 4c8c: 08 95 ret Wth this commit it gets translated to: 00004c40 <test>: 4c40: 28 2f mov r18, r24 4c42: 30 e0 ldi r19, 0x00 ; 0 4c44: 46 2f mov r20, r22 4c46: 50 e0 ldi r21, 0x00 ; 0 4c48: 86 17 cp r24, r22 4c4a: 20 f0 brcs .+8 ; 0x4c54 <test+0x14> 4c4c: c9 01 movw r24, r18 4c4e: 84 1b sub r24, r20 4c50: 95 0b sbc r25, r21 4c52: 08 95 ret 4c54: c9 01 movw r24, r18 4c56: 84 1b sub r24, r20 4c58: 95 0b sbc r25, r21 4c5a: 93 95 inc r25 4c5c: 08 95 ret There is not much performance improvement in this case, however at least with this commit it functions correctly. Note: The following commit will improve compiler output for the latter example. * tmk_core/common: Improve code generation for TIMER_DIFF* macros Because of integer promotion the compiler is having a hard time generating efficient code to calculate TIMER_DIFF* macros in some situations. In the below example, the return value is "int", and this is causing the trouble. Example C code: int __attribute__ ((noinline)) test(uint8_t current_timer, uint8_t start_timer) { return TIMER_DIFF_8(current_timer, start_timer); } BEFORE: (with -Os) 00004c40 <test>: 4c40: 28 2f mov r18, r24 4c42: 30 e0 ldi r19, 0x00 ; 0 4c44: 46 2f mov r20, r22 4c46: 50 e0 ldi r21, 0x00 ; 0 4c48: 86 17 cp r24, r22 4c4a: 20 f0 brcs .+8 ; 0x4c54 <test+0x14> 4c4c: c9 01 movw r24, r18 4c4e: 84 1b sub r24, r20 4c50: 95 0b sbc r25, r21 4c52: 08 95 ret 4c54: c9 01 movw r24, r18 4c56: 84 1b sub r24, r20 4c58: 95 0b sbc r25, r21 4c5a: 93 95 inc r25 4c5c: 08 95 ret AFTER: (with -Os) 00004c40 <test>: 4c40: 86 1b sub r24, r22 4c42: 90 e0 ldi r25, 0x00 ; 0 4c44: 08 95 ret Note: the example is showing -Os but improvements can be seen at all optimization levels, including -O0. We never use -O0, but I tested it to make sure that no extra code is generated in that case.OA * quantum/debounce: Fix custom wrapping timers in eager_pr and eager_pk debounce algorithms Please see the below simulated sequence of events: Column A is the 16-bit value returned by read_timer(); Column B is the value returned by custom_wrap_timer_read(); Column C is the original code: (timer_read() % MAX_DEBOUNCE) A, B, C 65530, 19, 30 65531, 20, 31 65532, 21, 32 65533, 22, 33 65534, 23, 34 65535, 24, 35 0 25, 0 1, 26, 1 2, 27, 2 3, 28, 3 4, 29, 4 5, 30, 5 read_timer() wraps about every 1.09 seconds, and so debouncing might fail at these times without this commit. * quantum/debounce/eager_pr and eager_pk: modifications for code readability according to code review. * quantum/debounce/eager_pr and eager_pk: modifications for code readability according to code review.

* Fix compile issues related to NO_ACTION_MACRO/FUNCTION and LTO_ENABLE (#8663)Konstantin Đorđević2020-04-091-0/+10
| | | | | | | | | | | | | | | | * Define NO_ACTION_MACRO/FUNCTION in header instead of makefile when LTO is enabled Currently, boards and keymaps that define NO_ACTION_MACRO/FUNCTION unconditionally will not compile with LTO_ENABLE (#8604). This fixes the issue by moving the definitions from common.mk to action.h, which enables us to check for previous definitions of those macros (this cannot be done in a makefile). * Remove LTO checks in templates Since now NO_ACTION_MACRO/FUNCTION are defined as needed in action.h (which is included by quantum.h), checking for LTO in keyboard and user code is no longer required. * Update LTO_ENABLE docs
