0be3fe9ab4 - removed TWasmObjData.AddFuncType, instead call directly [F]FuncTypes.AddOrGetFuncType 2023-12-31 15:52:27 +02:00

7266981c6c + Extracted the func list maintenance functionality from the WebAssembly object 
writer to a new TWasmFuncTypeTable class. This will allow for it to be reused
  in the WebAssembly exe writer as well.

Nikolay Nikolov
bc727f9fb2 + added TWasmObjInput class. To be used in the WASM internal linker. Not doing anything, yet. 2023-11-15 01:39:39 +02:00
Nikolay Nikolov
322befbf56 + added mutable globals to the target switches section 2023-06-17 17:00:36 +03:00

Nikolay Nikolov
dd13b46088 * use WasmCustomSectionName to obtain the debug section names in MaybeWriteDebugSection and MaybeAddDebugSectionToSymbolTable 2022-08-03 23:11:44 +03:00
Nikolay Nikolov
efd92fba01 + introduced TWasmCustomDebugSectionType 2022-08-03 23:04:53 +03:00
Nikolay Nikolov
cc260eb7b2 * wasm32 obj writer: use Data.ObjSectionList.Find to find the debug section by name in MaybeWriteDebugSection 2022-08-03 22:02:19 +03:00
Nikolay Nikolov
e959422753 * wasm32 obj writer: do the relocations before writing the code, data and debug sections 2022-08-03 20:56:44 +03:00
Nikolay Nikolov
edf5fce7e3 * wasm32 obj writer: determine the section number for the datacount, code, data and debug sections ahead of time (before writing the sections) 2022-08-03 20:51:58 +03:00
Nikolay Nikolov
b5a71086e8 * wasm32 obj writer: moved the writing of the data sections ahead 2022-08-03 20:44:11 +03:00
Nikolay Nikolov
2a196899bc * wasm32 obj writer: writing the debug section symbols to the symbol table moved before the writing of the debug sections themselves 2022-08-03 20:36:50 +03:00
Nikolay Nikolov
65b4425672 + support declaring wasm globals in the WebAssembly internal object writer 2022-07-31 19:28:09 +03:00

Nikolay Nikolov
63c8e458bb * workaround crash when generating WebAssembly DWARF debug info for threadvars, while multithreading is turned off 2022-07-16 19:31:14 +03:00
Nikolay Nikolov
fcadc80163 * don't write R_WASM_TABLE_INDEX_I32 relocations, always use R_WASM_FUNCTION_OFFSET_I32 in debug sections 2022-07-16 19:08:06 +03:00
Nikolay Nikolov
972a9df031 + always (even when multithreading is off) create a "target features" section 
in the WebAssembly object writer, since we still require some (very commonly
  supported) extensions, even without multithreading
 2022-07-16 07:42:53 +03:00
Nikolay Nikolov
bf17a84dd2 + implemented the R_WASM_FUNCTION_OFFSET_I32 relocation in the WebAssembly object writer 2022-07-16 04:34:15 +03:00
Nikolay Nikolov
6a94d2683b + emit WASM DWARF debug info relocations 2022-07-16 04:19:50 +03:00
Nikolay Nikolov
90305b6032 + write the actual DWARF debug sections in the WebAssembly object writer. The relocations aren't ready, yet, though. 2022-07-16 02:13:42 +03:00
Nikolay Nikolov
b82af25e63 * fixed crashes with the WebAssembly internal object writer, when debug info is enabled. The debug info itself is not yet written to the file, though. 2022-07-16 01:40:21 +03:00
Nikolay Nikolov
a9698b6f6e + introduced TWasmObjSection.IsDebug 2022-07-16 00:54:11 +03:00
Nikolay Nikolov

Nikolay Nikolov
ee89b7c9ec * fixed warning 2022-05-28 00:47:23 +03:00
Nikolay Nikolov
0c6287894b * the WebAssembly internal assembler renamed WASM (previously it was OMF, which was the ID of the MS-DOS .obj writer, which I forgot to rename) 2022-05-26 14:12:10 +03:00
Pierre Muller
7c21b37105 Avoid some range check error and convert internalerror into error messages 2022-05-26 00:28:47 +02:00
Pierre Muller
c9e8bfd118 Add internalerror if ogwasm tries to write unset Func/Global or TagIndex of TWasmObjSymbol 2022-02-11 22:19:43 +00:00
Nikolay Nikolov
cdf1ceca76 * emit a weak symbol for the exception tag, since that's what the LLVM linker 
wants to treat them as shared between .o files
 2021-09-28 02:52:40 +03:00
Nikolay Nikolov
b463f2a141 + added support for exception tags and for the 'throw' and 'catch' instructions 
in the wasm internal assembler and object writer
 2021-09-27 21:44:09 +03:00
Nikolay Nikolov
b46c010f82 + also support immutable wasm globals in the wasm assembler writer (both internal and external) 2021-09-27 05:40:26 +03:00
Nikolay Nikolov
7b31549119 * the data section is now only written by the internal wasm object writer, when 
there are data segments in the module
 2021-09-27 05:17:20 +03:00
Nikolay Nikolov
e85aff2b96 * combined TWasmObjSymbol.ImportIndex and .FuncIndex into just .FuncIndex, 
because there's no point in having them separate, and the name ImportIndex
  is misleading, as there are multiple import indices (they are separate for
  functions, globals, tables, memories, etc.)
 2021-09-27 04:53:35 +03:00
Nikolay Nikolov
2bce4d36db + proper support for WASM globals in the internal object writer - emit 
relocations, generate a Global section, if they are declared in the object
  file, etc.
 2021-09-27 04:24:49 +03:00
Nikolay Nikolov
5ad2d47e23 * track wasm global types in the internal object writer 2021-09-27 03:03:57 +03:00
Nikolay Nikolov
0bb781c928 * omit writing the export section if there are no exported functions from 
the module. This reduces object file size slightly for modules without
  exports.
 2021-09-26 23:14:52 +03:00
Nikolay Nikolov
d37117c460 * use an incrementing counter variable to determine the numbers for the code 
and data section, so they can be used in the relocation section, without
  hardcoding them as constants. This will automatically adjust the numbers
  when we add more sections, or when we make writing some of the sections
  optional.
 2021-09-26 23:10:55 +03:00
Nikolay Nikolov
77b898fe45 * use objsym.size to determine the code size of the function (instead of 
writing until the end of the section) in the wasm internal object writer.
  This removes the extra padding of 'unreachable' instructions at the end of
  each function (which are zeroes, added for alignment - they are harmless,
  but are unnecessary and cause a slight increase of the size of the
  resulting binaries), after the final 'return' instruction of the function.
 2021-09-26 22:21:34 +03:00
Nikolay Nikolov
2102fbdc97 - removed debug writelns from the wasm internal object writer 2021-09-26 20:13:35 +03:00

Nikolay Nikolov
c881d05793 * fixed bug in the code, generated for the RELOC_FUNCTION_INDEX_LEB 
relocation
 2021-09-26 10:29:17 +03:00
Nikolay Nikolov
07461d0fc3 * made the constructor of TObjSymbol virtual, so it can be overriden 2021-09-26 10:17:19 +03:00
Nikolay Nikolov
efd5831742 * generate an internal error if an attempt is made to emit a 
R_WASM_MEMORY_ADDR_LEB relocation, that points to code, instead of
  data
 2021-09-26 09:42:12 +03:00
Nikolay Nikolov
392ca81c20 + add threadvar symbols to the symbol table 2021-09-26 09:40:28 +03:00
Nikolay Nikolov
