Hello. We have various enum options that do not properly display options with --help=*: Apart from that, some of them are not separated by tabular, but with a space.
Using the suggested patch, --help=common will get: --- /tmp/before 2017-02-28 10:41:12.107024945 +0100 +++ /tmp/after 2017-02-28 10:41:32.615415978 +0100 @@ -193,7 +193,7 @@ -ffloat-store [disabled] -fforce-addr -fforward-propagate [disabled] - -ffp-contract= fast + -ffp-contract=[off|on|fast] fast -ffp-int-builtin-inexact [enabled] -ffunction-cse [enabled] -ffunction-sections [disabled] @@ -242,10 +242,10 @@ -fipa-sra [disabled] -fipa-struct-reorg -fipa-vrp [disabled] - -fira-algorithm= CB + -fira-algorithm=[CB|priority] CB -fira-hoist-pressure [enabled] -fira-loop-pressure [disabled] - -fira-region= [default] + -fira-region=[one|all|mixed] [default] -fira-share-save-slots [enabled] -fira-share-spill-slots [enabled] -fira-verbose=<number> 0x5 @@ -336,7 +336,7 @@ -fregmove -frename-registers [enabled] -freorder-blocks [disabled] - -freorder-blocks-algorithm= simple + -freorder-blocks-algorithm=[simple|stc] simple -freorder-blocks-and-partition [disabled] -freorder-functions [disabled] -freport-bug [disabled] @@ -386,7 +386,7 @@ -fshrink-wrap-separate [enabled] -fsignaling-nans [disabled] -fsigned-zeros [enabled] - -fsimd-cost-model= unlimited + -fsimd-cost-model=[unlimited|dynamic|cheap] unlimited -fsingle-precision-constant [disabled] -fsplit-ivs-in-unroller [enabled] -fsplit-loops [disabled] @@ -404,7 +404,7 @@ -fstack-protector-all [disabled] -fstack-protector-explicit [disabled] -fstack-protector-strong [disabled] - -fstack-reuse= all + -fstack-reuse=[all|named_vars|none] all -fstack-usage [disabled] -fstdarg-opt [enabled] -fstore-merging [disabled] @@ -489,7 +489,7 @@ -fvar-tracking-uninit [disabled] -fvariable-expansion-in-unroller [disabled] -fvect-cost-model - -fvect-cost-model= [default] + Specifies the cost model for vectorization. -fvect-cost-model=[unlimited|dynamic|cheap] [default] -fverbose-asm [disabled] -fversion -fvisibility=[default|internal|hidden|protected] default Ready to be installed after regression tests?
