Bug ID: 107017
Summary: RFE: support printf-style formatted functions in
-fanalyzer
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: dmalcolm at gcc dot gnu.org
Target Milestone: ---
We currently have some support for parsing the insides of a printf-style format
string in two places:
* gcc/c-family/c-format.cc: implements -Wformat in the C/C++ frontends, doing
type-checking on format strings against their arguments
* gcc/gimple-ssa-sprintf.cc: implements parts of -Wformat_overflow=,
-Wformat_truncation=, and -Wrestrict.
Now that the analyzer has -Wanalyzer-out-of-bounds, it might be good to
generalize this format-string parsing so that the analyzer can reuse it, and do
similar range analysis (but with the analyzer's more precise path-sensitive
interprocedural approach)

Should probably also handle scanf-style functions.
