Bug ID: 93229
Summary: simplify_count_trailing_zeroes doesn't compile on
x86_64-pc-linux-gnu
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: dmalcolm at gcc dot gnu.org
CC: wilco at gcc dot gnu.org
Target Milestone: ---
A pristine checkout of r280132 doesn't build for me on x86_64-pc-linux-gnu:
../../src/gcc/tree-ssa-forwprop.c: In function ‘bool
simplify_count_trailing_zeroes(gimple_stmt_iterator*)’:
../../src/gcc/config/i386/i386.h:2886:30: error: cannot convert ‘poly_uint16’
{aka ‘poly_int<1, short unsigned int>’} to ‘long int’ in assignment
2886 | ((VALUE) = GET_MODE_BITSIZE (MODE), TARGET_BMI ? 1 : 0)
| ~~~~~~~~~~~~~~~~~^~~~~~
| |
| poly_uint16 {aka poly_int<1, short
unsigned int>}
../../src/gcc/tree-ssa-forwprop.c:1925:22: note: in expansion of macro
‘CTZ_DEFINED_VALUE_AT_ZERO’
1925 | bool zero_ok = CTZ_DEFINED_VALUE_AT_ZERO (TYPE_MODE (type),
ctzval) == 2;
| ^~~~~~~~~~~~~~~~~~~~~~~~~
I'm assuming this was introduced in r280132, as that commit introduced
simplify_count_trailing_zeroes.
Am using gcc-9.2.1-1.fc30.x86_64 to try to build stage 1.
