IIUC, the syntax for an exact match is to put the search term between
double quotes:

https://www.google.com/search?q=%22gcc%22+%22altivec%22+%22vpmsum%22

which returns a few relevant(?) links such as

https://gcc.gnu.org/ml/gcc-patches/2015-08/msg01213.html
https://patchwork.ozlabs.org/patch/509083/
