508e0dd01c * WebAssembly internal linker: refactor writing the name custom section - group 
generating subsection data with the actual writing of the subsection data

cf7d9fa4c5 + WebAssembly internal linker: create a name custom section to help debugging 2024-09-17 05:34:20 +03:00
Nikolay Nikolov
aba44452f3 * WebAssembly internal linker: also don't remove unused data sections if 
smartlinking is turned off.
 2024-09-15 08:59:08 +03:00
Nikolay Nikolov
36ecb2b5da * WebAssembly internal linker: don't remove unused code sections if smartlinking 
is turned off. This is needed for debugging, because FPC doesn't support debug
  info with smartlinking on most platforms, and that includes WebAssembly.
 2024-09-15 08:32:35 +03:00
Nikolay Nikolov
562ca0ad80 * WebAssembly internal assembler writer: generate the function locals header 
when assembling the tai_local directive, instead of injecting them manually in
  TWasmObjOutput.WriteFunctionCode. This makes function code offsets correct
  and avoids the need to manually adjust relocation fixups by adding the locals
  header size. It also fixes relative relocations, used in DWARF debug line
  info.
 2024-09-15 03:44:14 +03:00

80523e192a * TWasmObjData.DeclareLocal renamed DeclareLocals. No functional changes. 2024-09-15 01:03:56 +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.
 2024-09-15 00:49:05 +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.
 2024-09-11 07:46:23 +03:00
Nikolay Nikolov
d81170ab23 * fix generation of addend for R_WASM_FUNCTION_OFFSET_I32 relocations. This 
improves code address accuracy for WebAssembly debug line info information.
 2024-09-11 04:50:35 +03:00
Nikolay Nikolov
b7742def46 + WebAssembly internal linker: support the R_WASM_GLOBAL_INDEX_I32 relocation, 
used for threadvar debug info, among another possible uses.
 2024-09-11 00:31:27 +03:00
Nikolay Nikolov
9799c6a5ec + support writing R_WASM_GLOBAL_INDEX_I32 relocations in the WebAssembly internal object writer 2024-09-11 00:12:20 +03:00
Nikolay Nikolov
ee98fa8e3f + WebAssembly internal linker: support data relocations to threadvars, resolve 
them as relative values to the beginning of the TLS section. Will be used for
  generating debug info for threadvars.
 2024-09-10 23:56:00 +03:00

424686ce34 * fix warning (second attempt :) ) 2024-09-07 18:05:35 +03:00
Nikolay Nikolov
a0cfed14fa * fix warning 2024-09-07 18:01:23 +03:00
Nikolay Nikolov
2ba0f42508 + WebAssembly internal assembler and linker: support exporting symbols from 
debug sections, via a FPC-specific extension. Unfortunately, this is not
  supported by the LLVM external assembler and linker.
 2024-09-07 17:07:29 +03:00
Nikolay Nikolov
27fd290150 + WebAssembly object writer: record the custom section index for debug sections 
in a new field TWasmObjSection.CustomSectionIdx
 2024-09-07 04:30:03 +03:00
Nikolay Nikolov
d79c549f03 * WebAssembly internal object writer: generate the symbol table after the 
section numbers have been calculated. This is preparation for exporting
  symbols from debug sections, which will be implemented in the future. No
  functional changes.
 2024-09-07 04:11:18 +03:00

4112318e2f * WebAssembly internal linker: allow specifying the max memory size also for 
binaries that don't use threads and shared memory. Unlike the shared memory
  case, in this case the max memory limit is optional.
 2024-08-22 10:51:02 +03:00
Nikolay Nikolov
44f58c702f * get rid of WebAssembly constant DefaultMaxMemoryForThreads, because it was 
repeated twice. Instead, set maxheapsize correctly with the default value in
  init_parser.
 2024-08-18 10:51:40 +03:00
Nikolay Nikolov
c54d1d4b89 * WebAssembly internal linker: the PageSize constant, which was repeated twice, 
moved to the class level and renamed WasmPageSize. No functional changes.
 2024-08-15 04:47:58 +03:00
Nikolay Nikolov
bf78823e60 + WebAssembly internal linker: take into account the min heap size (specified 
with the $M directive), when determining FMinMemoryPages
 2024-08-15 04:35:13 +03:00
Nikolay Nikolov
3218f25d13 * WebAssembly internal linker: reduced exe section alignment to 16 bytes 2024-08-11 03:57:05 +03:00

f81485a9b1 * WebAssembly threads internal linker: use signed LEB when needed in TWasmExeOutput.GenerateCode_InitTls and TWasmExeOutput.GenerateCode_InitSharedMemory 2024-08-11 02:55:15 +03:00
Nikolay Nikolov
2e2281387c * WebAssembly threads internal linker: micro optimization in 
TWasmExeOutput.GenerateCode_InitTls - skip generating instructions that add
  zero
 2024-08-11 02:44:23 +03:00
Nikolay Nikolov
4adb6b2bee * WebAssembly threads internal linker: use WriteUleb instead of WriteUleb5 in 
TWasmExeOutput.GenerateCode_InitTls and TWasmExeOutput.GenerateCode_InitSharedMemory.
  This generates equivalent, but shorter code.
 2024-08-11 02:37:18 +03:00
Nikolay Nikolov
dfe60b53d1 * WebAssembly threads internal linker: generate data.drop instructions in 
TWasmExeOutput.GenerateCode_InitSharedMemory. This drops the passive memory
  segments, after the memory has been initialized.

cfa7d6a0c6 * WebAssembly internal linker: moved the DataSections const array from local to 
the method writeData to local to the class. No functional changes.
