D.gnu - OS X bug: universal alpha indentifiers

unialpha.d:

 void anders() {}

 void main()

Gives the error:

Here's the disasm:

Similar errors for variables:

unialpha2.d:

 int anders;
 int björklund;
 
 void main()
 {
   anders = 1; björklund = 2;
 }


gdc:

 /var/tmp//cc7ur4wd.s:32:Parameter error: expression must be absolute

 /var/tmp//cc7ur4wd.s:32:Invalid mnemonic '?rklundi-L1$pb)(r9)'


asm:

 	la r9,lo16(__D9unialpha210björklundi-L1$pb)(r9)



Not sure how this can be fixed, without
changing the way that D mangles the names...

Both programs compile just fine on Linux.

If you are feeling like testing or something,
here are the rest of the Universal Alphas :

http://www.algonet.se/~afb/d/universalalphas/



 Identifiers start with a letter, _, or unicode alpha, and are followed
 by any number of letters, _, digits, or universal alphas. Universal
 alphas are as defined in ISO/IEC 9899:1999(E) Appendix D. (This is the
 C99 Standard.)

I think Walter officially acknowledged the phrase
"unicode alpha" as just a typo for universal...
(the meaning is that it can't start with a digit)

I've been only testing the name mangling, thus it shouldn't be important what
scripts I check.

This shoulde be clarified. I suppose that "digits" are only "0123456789" -
there are loads of other digits in Unicode.

Why is an ancient (1999) version used in the documentation? I've tried
codepoints that are assigned in the current standard bu
weren't in the 1999 one, and as you might have guessed even currently reserved
codepoints weren't caught by the frontent...

Yes, the quoted C99 standard (which isn't all that "ancient") used:

 Digits: 0660-0669, 06F0-06F9, 0966-096F, 09E6-09EF, 0A66-0A6F,
 0AE6-0AEF, 0B66-0B6F, 0BE7-0BEF, 0C66-0C6F, 0CE6-0CEF, 0D66-0D6F,
 0E50-0E59, 0ED0-0ED9, 0F20-0F33


But I'm also thinking that a "digit" here meant [0-9]...
I think a "letter" to Walter is just [a-zA-Z], as well ?

And I agree, it would be a lot easier to just say that.
