29ee863e8f - WebAssembly code generator: removed the g_fingerprint hack, that added 4 
useless i64 constants on the stack with random numbers and then drop them. It
  was used for primitive debugging, since previously it wasn't possible to
  identify the function name. Now we can produce DWARF debug info, as well as a
  "names" custom section to give each function a name and most WebAssembly
  environments support at least one of the two mechanisms. Therefore the
  g_fingerprint hack is no longer necessary.

1a08d76ccb + WebAssembly: insert a tai_local directive also for assembler functions 2024-09-15 02:12:48 +03:00
Nikolay Nikolov
b9ca30165c * WebAssembly: refactored tai_local, so that it is a single directive, 
containing multiple locals, instead of creating multiple tai_local directives,
  each containing a single local. No functional changes.

05b67c7408 - WebAssembly: removed tai_local.name, because we don't use it 2024-09-15 00:09:39 +03:00
Nikolay Nikolov
99943610cb * WebAssembly: generate the final bashB opcode of a function via the 
end_function instruction, instead of adding it magically in the object writer.
  This makes the WebAssembly debug line info more accurate, covering the
  end_function instruction as well.
