The ldbl-96 implementation of j1l has some function-local variables that are declared static for no apparent reason (this dates back to the first addition of that file). Any vaguely recent compiler, probably including any that are supported for building glibc, optimizes away the "static" here, as the values of the variables on entry to the function are dead. So there is not actually a user-visible bug here at present (but with any compilers that didn't optimize away the static at all, possibly building with less or no optimization, so that the function stored intermediate values to and then loaded them from the variables, there would have been a thread-safety issue). But the "static" clearly doesn't belong there and might potentially make things unsafe were compilation without optimization to be supported in future, so this patch removes it. Tested for x86_64. * sysdeps/ieee754/ldbl-96/e_j1l.c (qone): Don't make local variables static. |
