Already since r231651 (if my old notes are to be believed...), we've been
seeing this issue for 'g++.dg/eh/alias1.C' (before: 'sorry, unimplemented:
target cannot support nonlocal goto'), and still do now:
FAIL: g++.dg/eh/alias1.C -std=gnu++98 (internal compiler error)
[etc.]
during RTL pass: vregs
[...]/gcc/testsuite/g++.dg/eh/alias1.C: In function 'void g(int)':
[...]/gcc/testsuite/g++.dg/eh/alias1.C:20:1: internal compiler error: in
instantiate_virtual_regs_in_insn, at function.c:1739
0xb5214b instantiate_virtual_regs_in_insn

0xb5214b instantiate_virtual_regs
[...]/gcc/function.c:1977
0xb5214b execute
[...]/gcc/function.c:2026
(Ever since they got added?) we'd also seen this issue for
'g++.dg/ext/pr84724-1.C', 'g++.dg/ext/pr84724-2.C', but the ICE then
disappeared in (r265343, r265570].
Since (r259629 ,r261792] we also saw this issue for 'gcc.dg/graphite/pr82321.c'
(before: 'PASS'), then the ICE disappeared in (r271346, r272643], and now in
cff5a231480526aa73094a22fe8b2f39b63735a4..c416c52bcdb120db5e8c53a51bd78c4360daf79b
it has re-appeared:
[-PASS:-]{+FAIL: gcc.dg/graphite/pr82321.c (internal compiler error)+}
{+FAIL:+} gcc.dg/graphite/pr82321.c (test for excess errors)
during RTL pass: vregs
[...]/gcc/testsuite/gcc.dg/graphite/pr82321.c: In function 'dm':
[...]/gcc/testsuite/gcc.dg/graphite/pr82321.c:36:1: internal compiler
error: in instantiate_virtual_regs_in_insn, at function.c:1739

[...]/gcc/function.c:1739
0x8ffedb instantiate_virtual_regs
[...]/gcc/function.c:1977
0x8ffedb execute
[...]/gcc/function.c:2026
These are all the instances of this ICE, per my records.

nvptx: Define TARGET_TRULY_NOOP_TRUNCATION to false
Many thanks to Richard Biener for approving the midde-end
patch that cleared the way for this one. This nvptx patch
defines the target hook TARGET_TRULY_NOOP_TRUNCATION to
false, indicating that integer truncations require explicit
instructions. nvptx.c already defines TARGET_MODES_TIEABLE_P
and TARGET_CAN_CHANGE_MODE_CLASS to false, and as (previously)
documented that may require TARGET_TRULY_NOOP_TRUNCATION to
be defined likewise.
This patch decreases the number of unexpected failures in
the testsuite by 10, and increases the number of expected
passes by 4, including these previous FAILs/ICEs:
gcc.c-torture/compile/opout.c
gcc.dg/torture/pr79125.c
gcc.dg/tree-ssa/pr92085-1.c
Unfortunately there is one testsuite failure that used to
pass gcc.target/nvptx/v2si-cvt.c, but this isn't an ICE or
incorrect code. This regression has been filed as PR96403,
and the failing scan-assembler directives have been replaced
by a reference to the PR.
This patch has been tested on nvptx-none hosted on
x86_64-pc-linux-gnu with "make" and "make check" with
fewer ICEs and no wrong code regressions.
