a4672fbd1c o based on a patch by Rika, resolves #39401: 
* use Base64 (62=_, 63=$) encoded FNV hash (instead of CR-32) to shorted identifiers
    * renamed fpccrc to fpchash
    + test

bae50d80d2 * preopen fd names and current dir changed to use ansistring, as well as the 
parameters and result of ConvertToFdRelativePath. This will allow easier
  implementation of ChDir.

7388735b11 * Strength reduction optimization: - Use a temp for complex loop start values to prevent double evaluation. 
- For slow CPUs perform the optimization for all sizes of array elements.

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.

fab4ca449b * twasmexceptionstatehandler_nativeexceptions.handle_nested_exception and 
twasmexceptionstatehandler_bfexceptions.handle_nested_exception should not be

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
 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)

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.
