Feature List

There is always a problem to create a list of new features when a new SDCC release is announced. The following list is an attempt to create such a list "on the fly". Every time a new feature which is visible or interesting for the SDCC users is implemented, it should be added to the following list.

• C2X bit-precise integer types and bit-fields thereof for (except for pic14, pic16).
• Added all new general mnemonics from ASxxxx 5.40 except for .bank and enabled for all ports
• sm83: sdasgb now can output cycles in listing and sz80 has accurate cycles for this processor except for branching
• struct / union return (except for ds390, hc08, s08, mos6502, pic14, pic16).
• div standard library function family.
• struct / union parameters (except for hc08, s08, mos6502, pic14, pic16).
• C2X nullptr.
• Many fixes for the type system and _Generic.
• Adopted more of GCC, QuickC and tinycc tests.
• C2X char8_t.
• C2X memalignment.
• C2X unreachable.
• C2X typeof, typeof_unqual.
• C2X auto.
• C2X keywords bool, true, false, alignas, alignof, static_assert.
• C90-C17 function declarators without prototypes.
• C99 variably modified types.
• C2X bit and byte utilities.
• call_once.
• _sdcc_external_startup renamed to __sdcc_external_startup and supported for all ports.
• makeshift support for long double as another alias for float.

Was this removed on purpose?

This one you have already reverted, though without the @

Greets,

Thanks for having an eye on this. This is not the first time I accidentially reverted something when editing a wiki page. I think Sourceforge sometimes uses an old page version when I click "Edit".

SDCC 4.3.0 RC1 is available?
Planned date was 2023-06-02.
I got the yesterday night build but SDCC crash on Win10/64 about ccl1 error.

[Philipp Klaus Krause]

It was delayed to fix some issues.
