2012-02-24new attempt at working around the gcc 3 visibility bugRich Felker-0/+4
since gcc is failing to generate the necessary ".hidden" directive in the output asm, generate it explicitly with an __asm__ statement...
2012-02-24remove useless attribute visibility from definitionsRich Felker-1/+1
this was a failed attempt at working around the gcc 3 visibility bug affecting x86_64. subsequent patch will address it with an ugly but working hack.
2012-02-23cleanup and work around visibility bug in gcc 3 that affects x86_64Rich Felker-6/+4
in gcc 3, the visibility attribute must be placed on both the declaration and on the definition. if it's omitted from the definition, the compiler fails to emit the ".hidden" directive in the assembly, and the linker will either generate textrels (if supported, such as on i386) or refuse to link (on targets where certain types of textrels are forbidden or impossible without further assumptions about memory layout, such as on x86_64). this patch also unifies the decision about when to use visibility into libc.h and makes the visibility in the utf-8 state machine tables based on libc.h rather than a duplicate test.
2011-03-25fix all implicit conversion between signed/unsigned pointersRich Felker-1/+1
sadly the C language does not specify any such implicit conversion, so this is not a matter of just fixing warnings (as gcc treats it) but actual errors. i would like to revisit a number of these changes and possibly revise the types used to reduce the number of casts required.
2011-02-27cleanup utf-8 multibyte code, use visibility if possibleRich Felker-84/+5
this code was written independently of musl, with support for a the backwards, nonstandard "31-bit unicode" some libraries/apps might want. unfortunately the extra code (inside #ifdef) makes the source harder to read and makes code that should be simple look complex, so i'm removing it. anyone who wants to use the old code can find it in the history or from elsewhere. also, change the visibility of the __fsmu8 state machine table to hidden, if supported. this should improve performance slightly in shared-library builds.
