a62c7555d7 - removed the DebugWriteXXX functions from the WASI system unit, since console 
output is now quite stable and can be used for debugging

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

compiling in WebAssembly branchful exceptions mode

30b503abc4 * instead of using the 'throw' intrinsic, set a boolean flag, in the branchful 
exceptions support code
 2021-10-05 00:49:29 +03:00
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)
 2021-10-05 00:37:20 +03:00

3836b0be04 * longjmp in fpc_reraise changed to a throw instruction intrinsic in wasm native exceptions mode 2021-09-28 04:02:52 +03:00
Nikolay Nikolov
0c3e179652 - get rid of fpc_PushExceptAddr and fpc_PopAddrStack entirely, when compiling in 
wasm native exceptions mode - these helper routines aren't necessary in this
  mode
 2021-09-28 03:59:38 +03:00
Nikolay Nikolov
91f0f1a86c * don't include except.inc if wasm32 native exception is turned on, instead 
replace it with except_native.inc
 2021-09-28 03:46:30 +03:00
Nikolay Nikolov
73bc8edef3 + RTL support for raising exceptions in native wasm exceptions mode 2021-09-28 03:31:04 +03:00
Nikolay Nikolov
33e25a3dfe + added except_native.inc include file (empty for now, but will provide RTL 
support for the native wasm exceptions in the future)
 2021-09-18 03:08:48 +03:00
Nikolay Nikolov
c2754eac3f + introduced the wasm32_throw_fpcexception inline function, that emits a 
'throw' instruction. This way we'll be able to emit this instruction from
  RTL code (i.e. from fpc_raiseexception, when that is implemented for
  WebAssembly)
