kconfig: warn of unhandled characters in Kconfig commands

2015-08-19T15:05:39+00:00

In Kconfig, definitions of options take the following form: " ...". COMMANDs and PARAMs are treated slightly different by the underlying parser. While commit 2e0d737fc76f ("kconfig: don't silently ignore unhandled characters") introduced a warning for unsupported characters around PARAMs, it does not cover situations where a COMMAND has additional characters before it. This change makes Kconfig emit a warning if superfluous characters are found before COMMANDs. As the 'help' statement sometimes is written as '---help---', the '-' character would now also be regarded as unhandled and generate a warning. To avoid that, '-' is added to the list of allowed characters, and the token '---help---' is included in the zconf.gperf file.

kconfig: allow use of relations other than (in)equality

2015-06-15T12:05:58+00:00

Over the years I found it desirable to be able to use all sorts of relations, not just (in)equality. And apparently I'm not the only one, as there's at least one example in the tree where the programmer assumed this would work (see DEBUG_UART_8250_WORD in arch/arm/Kconfig.debug). Another possible use would e.g. be to fold the two SMP/NR_CPUS prompts into one: SMP could be promptless, simply depending on NR_CPUS > 1. A (desirable) side effect of this change - resulting from numeric values now necessarily being compared as numbers rather than as strings - is that comparing hex values now works as expected: Other than int ones (which aren't allowed to have leading zeroes), zeroes following the 0x prefix made them compare unequal even if their values were equal.

kconfig: remove unused definition from scanner

2013-10-08T21:52:15+00:00

The definition ws [ \n\t] is not used anywhere. Drop it to avoid confusion. As it is a dead definition, any changes in the resulting code generated by flex would be surprising (actually testing this showed that there are really no changes). So, there is no need to touch the existing zconf.lex.c_shipped. Signed-off-by: Martin Walch Reviewed-by: "Yann E. MORIN" Signed-off-by: "Yann E. MORIN:
