5bcc530707 * handle -<mm reg.> more cleverly if SSE is used 2021-09-18 22:11:03 +02:00
florian
5a2d884fe3 * is_calljmp really means calls and jmp 
* is_calljmpuncondret includes ret
 2021-09-18 19:24:53 +02:00
florian
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

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)
 2021-09-18 02:39:16 +03:00

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
