The attached patch corrects some errors in documentation of the --param
option to gcc. Mostly they are corrections to the names of options,
but two parameters are documented which do not exist in trunk.
gcc/ChangeLog:
* doc/invoke.texi (Optimize Options): In table of --param options
rename second occurrence of tracer-min-branch-ratio to
tracer-min-branch-probability, rename
tracer-min-branch-ratio-feedback to
tracer-min-branch-probability-feedback and clarify description,
rename sched-spec-state-edge-prob-cutoff to
sched-state-edge-prob-cutoff, rename selsched-max-insns-to-rename
to selsched-insns-to-rename, rename lto-minpartition to
lto-min-partition, delete reorder-blocks-duplicate and
reorder-blocks-duplicate-feedback.
