Bug ID: 86263
Summary: [nvptx] casesi, tablejump
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
CC: marxin at gcc dot gnu.org, vries at gcc dot gnu.org
Target Milestone: ---
Target: nvptx
As of trunk r261793 "Switch other switch expansion methods into classes"
(Martin CCed, but this might have been a latent bug already?) GCC for nvptx
target fails to build its target libraries: "internal compiler error: in
emit_case_dispatch_table, at stmt.c:851". That's emit_case_dispatch_table
complaining that neither casesi or tablejump are implemented for nvptx, which
is documented there as a requirement (is that for this code patch only, now
taken erroneously?):
First we try "casesi". If that
fails, try "tablejump". A target *must* have one of them (or both).
