wingo pushed a commit to branch lightning
in repository guile.

commit 100fbd17fb668b40a82c4c51b4e4c552f289730c

    Change JIT_FPR_NUM to 7 to prevent clobber of JIT_FPR(7)
    
      Lightning provides at least 6 float registers, so, in this commit,
    reduce from 8 to 7 so that code respecting JIT_FPR_NUM should be
    safe again't use of JIT_FPTMP.
