7afb665c92 + insert exception flag check and branch after each function call, when 
compiling in WebAssembly branchful exceptions mode

5be1bfeeca + added comment that states that raiseBr is only used in branchful exceptions mode 2021-10-05 01:11:31 +03:00
Nikolay Nikolov
d02921d66b + introduced raiseBr, similar to exitBr, but will point to the current 
innermost exception handler, if there is such a handler in the current
  procedure, otherwise it will be the same as exitBr.

6599f1d898 - don't generate any WebAssembly native exception handling instructions, nor 
relocations, when compiling in branchful exceptions mode. This produces a
  currently not working, but accepted by wasmtime binary (otherwise, it
  complains it doesn't support exceptions and refuses to try to run it).

30b503abc4 * instead of using the 'throw' intrinsic, set a boolean flag, in the branchful 
exceptions support code

Nikolay Nikolov
5124ab2521 * cloned the WebAssembly native exceptions code generation and rtl support into 
the branchful exceptions (which will be modified later, but we're using this
  as their starting point, because we can get a snapshot built, without compiler
  internal errors)

c745ae4836 AArch64 popt: don't replace registers with X/WZR 
Most arithmetic/logica instructions don't support X/WZR as operand (since
you should use movk with the calculated constant in that case)

e9d318e7e2 * x86: Fixed update of used registers in the CMOV optimizations. 
This fixes a bug reported by Martin Frb in fpc-devel which is triggered
  by the recently provided test code in FPC 3.2.2 x86_64, but is hidden
  in trunk by other pipeline peephole optimizations.

ab01b0ebd7 Typed constants: no internalerror on failure 
Don't check whether the expression queue is empty in the destructor in case
there was an error. Also improved error messages (constant expression instead
of variable expression expected).
