[bug-gperf] 1 bug and some feature requests

[Denis Naumov]

Hi,

BUG:
I found that gperf can't work with utf-8 encoded input file.
If utf-8 input file have signature (start bytes EF BB BF) then gperf
generate error
"example.gperf:7: %} outside of %{...%} section".

FEATURE REQUEST 1:
There is command line option "-m" (--multiple-iterations). Is it
possible to create
option equivalent for declaration section. Something like %iterations-count=XXX.
It's easy and comfortable to place all possible options in declaration
section and don't use command line.

FEATURE REQUEST 2:
Is it possible to add wchar_t* unicode strings support for perfect
hash function?

FEATURE REQUEST 3:
Is it possible to create calling convention option?
Something like %calling-convention __fastcall / __cdecl / __stdcall
If it is specified - then calling convention is placed in code.
If not - no calling convention is placed in code (determined by compiler).

BUG-OR-NOT:
If I use %global-table option then I have lengthtable and wordlist
arrays as global variables? but
asso_values in hash function is still local. Is it bug?

Thanks.

Sorry for poor English.

Best regards,
Denis.
