PR middle-end/79692 - [7 Regression] -Wformat-overflow false positive
gcc/ChangeLog:
PR middle-end/79692
* gimple-ssa-sprintf.c
(directive::known_width_and_precision): New function.
(format_integer): Use it.
(get_mpfr_format_length): Consider the full range of precision
when computing %g output with the # flag. Set the likely byte
count to 3 rather than 1 when precision is indeterminate.
(format_floating): Correct the lower bound of precision.
gcc/testsuite/ChangeLog:
PR middle-end/79692
* gcc.dg/tree-ssa/builtin-sprintf-2.c: Add test cases.
* gcc.dg/tree-ssa/builtin-sprintf-warn-10.c: Correct %#g.
* gcc.dg/tree-ssa/builtin-sprintf-warn-15.c: New test.
* gcc.dg/tree-ssa/builtin-snprintf-3.c: Ditto.
