Investigate AppleWin.exe's increase in file-size

[tomcw]

From AppleWin 1.25 to 1.26, the EXE size has increased by 644K:

• 1.25.0.4: 1,620K
• 1.26.3.6: 2,290K

---

Notes:

1.26.3.6(master): 2,293K

• new logo bitmap: +631K
  • (old logo bitmap: 212K) - in vcproj only (removed at e1ee664), not in rc script
• new yaml lib : +328K (NB. not all code)
• now built with VS2008 (was VS2005)
• updated to latest zlib.lib

Switch to old logo: file size = 1,874K - still +254K bigger than v1.25

• all from yaml lib?

remove yaml.lib: file size = 1,759K - still +139K bigger than v1.25

• So yaml.lib accounts for 115K (!)

Why is file size still +139K (cf v1.25)?

Linker: eliminate unreferenced data /OPT:REF (enabled at e1ee664)

• file size = 1,550K
• what has been eliminated?
• NB. not enabled in VS2005 vcproj

re-add yaml.lib:

• file size = 1,661K
• so yaml.lib still accounting for 111K (!)

• From map file: 0001:0008c4a0 _yaml_get_version_string 0048d4a0 f yaml:api.obj : 0001:000a1950 _yaml_parser_update_buffer 004a2950 f yaml:reader.obj 0001:000a244b ?_Xlen@_String_base@std@@SAXXZ 004a344b f libcpmt:string.obj

  Static symbols: 0001:0008d0e0 _yaml_string_read_handler 0048e0e0 f yaml:api.obj : 0001:000a2330 _yaml_parser_update_raw_buffer 004a3330 f yaml:reader.obj 0001:000a2560 __onexit_nolock 004a3560 f LIBCMT:onexit.obj

• so yaml.lib (.text) contribution = union of above overlapping symbols (90K & 87K funcs)

re-add AppleWinLogo.bmp:

• file size = 2,080K

Linker: COMDAT folding

• file size = 2,080K (no affect)

NB: zip support added at 1.18.0 1.17.1 -> 1.20.0: file size increases by 100K (1500K->1600K) Current:

• zip_lib lib: 177K
• zlib lib : 412K

TODO:

• [ ] build with VS2005
• [ ] build with old zlib lib
• [ ] can logo resource be compressed?
  • compress logo (bmp->png): 631K->115K
  • compress logo (bmp->zip): 631K-> 83K
• [ ] WinGDI has some png support:
  • BITMAPINFOHEADER.biCompression = BI_PNG
