Bug ID: 109371
Summary: MIN_EXPR/MAX_EXPR and SMIN/SMAX trapping behavior is
not documented
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: documentation, internal-improvement
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
I noticed while working on phi-opt, that MIN/MAX EXPR were actually not
documented in generic.texi and even the behavior of trapping was not documented
for RTL.
There was a patch in 2019 about this:
https://inbox.sourceware.org/gcc-patches/20190822134551.18924-2-...@linux.ibm.com/
But I am not sure where it ended up.
Note I also wrote
https://inbox.sourceware.org/gcc/CA+=sn1keyne62f6bj_hemfqnr_m1yokzrqupkdqtqswxfz0...@mail.gmail.com/T/#u
asking about the behavior of trapping with respect to -ffinite-math-only too
because that is where I noticed a difference in how different parts of phi-opt
handle things even.
