2012-03-19i386: Convert libc_{feholdexcept_setround,updateenv}_53bit to functions.Richard Henderson1-29/+29
Also fix a bug in libc_feupdateenv_53bit: don't force the rounding precision back to _FPU_EXTENDED, instead restore the precision that the user had in effect beforehand.

2011-12-23Fix wrong copying processing for last bytes in x86-32 wcscpyLiubov Dmitrieva1-41/+21
Wrong copy algorithm for last bytes, not thread safety. In some particular cases it uses the destination memory beyond the string end for 16-byte load, puts changes into that part that is relevant to destination string and writes whole 16-byte chunk into memory. I have a test case where the memory beyond the string end contains malloc/free data, that appear corrupted in case free() updates it in between the 16-byte read and 16-byte write.
