5a2d884fe3 * is_calljmp really means calls and jmp 
* is_calljmpuncondret includes ret

f78818e387 * some warnings fixed 2021-09-18 19:24:53 +02:00
Nikolay Nikolov
d3ec8f0d29 * generate an internalerror if there are values remaining on top of stack 
at the end of a procedure. If the compiler is compiled with
  DEBUG_WASMSTACK, the previous asm comment message is emitted instead of
  internal error.
 2021-09-18 18:10:57 +03:00
Nikolay Nikolov
324382d3a5 * use create_functype to determine accurately the number of parameters to 
discard in twasmcallnode.do_release_unused_return_value. This fixes
  various stack tracking bugs when a constructor is invoking another
  constructor, etc.

f7cc2d560c + initialize br_blocks in the thlcgwasm constructor 2021-09-18 16:29:19 +03:00
Nikolay Nikolov
a3610bfea1 + also added stack underflow check in thlcgwasm.incstack (in case stack 
height was already negative in the beginning, due to previous underflow)
 2021-09-18 16:28:14 +03:00
Nikolay Nikolov
d4bd1f1e9b * don't halt with an internal error, but add an asm comment instead, when a 
stack underflow is detected in thlcgwasm.decstack and when the compiler is
  compiled with the DEBUG_WASMSTACK define
 2021-09-18 16:28:14 +03:00
Nikolay Nikolov
58e4692795 * fixed thlcgwasm.g_adjust_stack_after_call after the removal of discardresult 2021-09-18 16:28:14 +03:00
Nikolay Nikolov
fa36141649 * fixed the stack tracking in twasmcallnode.do_release_unused_return_value for 
ret_in_param function calls

d292958665 * + .gitconfig with configuration for better diffing, needs a 
git config --local include.path ../.gitconfig

962c5bd727 x86: MOV constant optimisation 2021-09-18 08:30:50 +00:00
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
f76e91fb8b * cloned twasmtryexceptnode.pass_generate_code_no_exceptions into twasmtryexceptnode.pass_generate_code_native_exceptions 2021-09-18 02:52:24 +03:00
Nikolay Nikolov
334ea46b44 * cloned twasmraisenode.pass_1_no_exceptions into twasmraisenode.pass_1_native_exceptions 2021-09-18 02:48:51 +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)

ac2f299d04 + declare __FPC_exception as a label, otherwise wasm-ld crashes 2021-09-18 01:47:28 +03:00

try..finally in native wasm exceptions mode

exceptions
 2021-09-17 23:46:38 +03:00
Nikolay Nikolov
d8665f8a51 * write the .globaltype directive and the imports in the beginning of the 
assembly file, because that appears to be required by llvm-mc from git
 2021-09-17 23:46:38 +03:00

Nikolay Nikolov
619a27cbfc + insert try and end_try instructions in the try..finally code in native 
WebAssembly exceptions mode
 2021-09-17 21:09:17 +03:00
Nikolay Nikolov
45e53ddc16 * cloned the WASM no exceptions mode code generation for try..finally blocks 
for the native WASM exceptions mode. Eventually, it is going to be changed
  to support exceptions fully, and it's going to evolve separately, so this
  code is only used as a starting point
 2021-09-17 21:01:00 +03:00
Nikolay Nikolov
65a5b299c6 + introduced twasmraisenode.pass_1_no_exceptions 2021-09-17 16:53:35 +03:00

Nikolay Nikolov
c992566201 + introduced twasmtryexceptnode.pass_generate_code_no_exceptions, 
.pass_generate_code_js_exceptions and .pass_generate_code_native_exceptions
 2021-09-17 16:06:39 +03:00
Nikolay Nikolov
848098c63b * improvements to the handling of try..finally in WebAssembly no exceptions 
mode - even though exceptions aren't supported in this mode, the finally
  section is now executed in case of exit, break or continue
 2021-09-17 15:54:03 +03:00
Nikolay Nikolov
3601d61b81 + introduced twasmtryfinallynode.pass_generate_code_no_exceptions,
