Expanders do not have more elements in the operands array than declared in the pattern. So, we cannot use operands[5] here. Instead just declare and use another rtx. PR target/70668 * config/nds32/nds32.md (casesi): Don't access the operands array out of bounds. From-SVN: r235583

This patch adds support for the signed and unsigned int versions of the vec_adde altivec builtins from the Power Architecture 64-Bit ELF V2 ABI OpenPOWER ABI for Linux Supplement (16 July 2015 Version 1.1). There are many of the builtins that are missing and this is the first of a series of patches to add them. There aren't instructions for the int versions of vec_adde so the output code is built from other built-ins that do have instructions which in this case is just two vec_adds with a vec_and to ensure the carry vector is comprised of only the values 0 or 1. The new test cases are executable tests which verify that the generated code produces expected values. C macros were used so that the same test case could be used for both the signed and unsigned versions. An extra executable test case is also included to ensure that the modified support for the __int128 versions of vec_adde is not broken. The same test case could not be used for both int and __int128 because of some differences in loading and storing the vectors. Bootstrapped and tested on powerpc64le-unknown-linux-gnu with no regressions. Is this ok for trunk?
