PR tree-optimization/78696 - [7 Regression] -fprintf-return-value misoptimizes %.Ng where N is greater than 10
gcc/ChangeLog:
PR tree-optimization/78696
* gimple-ssa-sprintf.c (format_floating): Correct handling of
precision. Use MPFR for %f for greater fidelity. Correct handling
of %g.
(pass_sprintf_length::compute_format_length): Set width and precision
specified by asrerisk to void_node for vararg functions.
(try_substitute_return_value): Adjust dump output.
gcc/testsuite/ChangeLog:
PR tree-optimization/78696
* gcc.dg/tree-ssa/builtin-sprintf-5.c: Remove incorrect test cases.
* gcc.dg/tree-ssa/builtin-sprintf-warn-7.c: Correct off-by-1 errors.
* gcc.dg/tree-ssa/builtin-sprintf-warn-9.c: New test.
* gcc.dg/tree-ssa/builtin-sprintf.c: Add test cases.
