Bug ID: 111161
Summary: [13 Regression] ICE: RTL check: expected code
'const_int', have 'reg' in riscv_print_operand, at
config/riscv/riscv.cc:4394 during build
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Keywords: build, ice-checking, ice-on-valid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: zsojka at seznam dot cz
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: riscv64-unknown-linux-gnu
Build: x86_64-pc-linux-gnu
I am currently failing to build the riscv64-unknown-linux-gnu cross-compiler on
the gcc-13-branch with RTL checking enabled:
Configure command line:
/repo/gcc-13-branch//configure --enable-languages=c,c++
--enable-valgrind-annotations --disable-nls --enable-checking=yes,rtl,df,extra
--with-cloog --with-ppl --with-isl --with-isa-spec=2.2
--with-sysroot=/usr/riscv64-unknown-linux-gnu --build=x86_64-pc-linux-gnu
--host=x86_64-pc-linux-gnu --target=riscv64-unknown-linux-gnu
--with-ld=/usr/bin/riscv64-unknown-linux-gnu-ld
--with-as=/usr/bin/riscv64-unknown-linux-gnu-as --disable-multilib
--disable-libstdcxx-pch
--prefix=/repo/gcc-13-branch//binary-13-branch-20230826002206-gc1732638180-checking-yes-rtl-df-extra-riscv64
Results in:

checking whether ln -s works... yes

-freport-bug).
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.
This only affects gcc-13-branch, probably only with RTL checking enabled.
I can't find the conftest.c file that is failing to build.
