074ce9c50f + added call to g_maybe_checkforexceptions after generating call to fpc_iocheck 2021-10-05 18:02:11 +03:00
Nikolay Nikolov
3c58f26e83 * thlcgwasm.g_checkexceptions renamed .g_maybe_checkforexceptions, added also as 
an empty virtual method in thlcgobj and modified the WebAssembly
  implementation, so that it can be called from any exceptions mode (so it
  emits no code in exception modes that don't require it, instead of generating
  an internal error). This will allow .g_maybe_checkforexceptions to be called
  from the generic parts of the code generator, after calls to systemprocs that
  could raise an exceptions.

387c80cc57 + default exception handling in WebAssembly native exceptions mode 2021-10-05 08:02:39 +03:00

fab4ca449b * twasmexceptionstatehandler_nativeexceptions.handle_nested_exception and 
twasmexceptionstatehandler_bfexceptions.handle_nested_exception should not be
  called, so now they cause an internal error

in the except 'on' statements, in branchful WebAssembly exceptions mode
 2021-10-05 06:25:32 +03:00

7110d1e48e * use 'br_if' instead of 'if br end_if' sequence in the code, generated by 
thlcgwasm.g_checkexceptions

d9eb8d75b9 + return a small, fake backtrace for WebAssembly, so that in case of a runtime 
error, the message 'Runtime error XXX at $EEEEEEEE' appears.

7afb665c92 + insert exception flag check and branch after each function call, when 
compiling in WebAssembly branchful exceptions mode
 2021-10-05 02:26:13 +03:00
Nikolay Nikolov
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).
