[Sdcc-user] binary constants for STM8?

[Georg Icking-Konert]

again hello,

in the SDCC manual I read "SDCC supports the use of binary constants,
such as 0b01100010. This feature is only enabled when the compiler is
invoked using –std-sdccxx"

However, calling SDCC for stm8 with –std-sdccxx fails with "syntax
error" for the literal and a warning that "option '-s' no longer
supported". And caliing it with -–std-sdccxx gives the same syntax error
and a warning "unknown compiler option '--std-sdccxx' ignored".

Does this mean that binary literals are not yet implemented for STM8...?
If they are, please let me know how to use them.

Thanks in advance!

Regards, Georg

Hello Georg,

You are kindly requested to replace the XX in --std-sdccXX with the year
of the C standard you wish to use. E.g. --std-sdcc99.

Further you seem to use different dashes before std.
