* Furi: optional message in furi_crash and furi_halt * Consistent furi_crash use * UnitTests: crash instead of assert * furi: check: fixed macro for default arg * unit_tests: fixed crashes everywhere * lib: infrared: fixed PVS warnings * furi: eliminated __FURI_ASSERT_MESSAGE_FLAG * Furi: update check.h docs * Furi: add check.h usage note * Docs: grammar --------- Co-authored-by: hedger <hedger@nanode.su>

/**

|
*
|
|
* Furi crash and assert functions.
|
|
*
|
|
* The main problem with crashing is that you can't do anything without disturbing registers,
|
|
* and if you disturb registers, you won't be able to see the correct register values in the debugger.
|
|
*
|
|
* Current solution works around it by passing the message through r12 and doing some magic with registers in crash function.
|
|
* r0-r10 are stored in the ram2 on crash routine start and restored at the end.
|
|
* The only register that is going to be lost is r11.
|
