[Tinycc-devel] [PATCH] Add __REDIRECT needed for Large File Support API on linux

[Ramsay Jones]

Since commit 9b09fc3 ("Add support of asm label for functions",
05-09-2010) tcc has had the capability to rename functions at the
assembly level. This capability was subsequently used by commit
2596273 ("Add support for __REDIRECT_NTH needed with eglibc",
11-09-2010) to redirect long double functions on platforms which
did not support long double.

Here we add the companion macro __REDIRECT which is used (along
with __REDIRECT_NTH) in the glibc headers on Linux to support the
Large File API (when _FILE_OFFSET_BITS is set to 64).

Hi,

This patch allows me to use tcc to compile git without warnings.
Without this patch, each use of readdir() or getrlimit() elicits
an "assignment from incompatible pointer type" warning.

[BTW, tcc builds git about 6x faster than gcc. The testsuite runs
about 6% slower.]

ATB,
Ramsay Jones
