--- Comment #11 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Rainer Orth <r...@gcc.gnu.org>: https://gcc.gnu.org/g:c4af8ebdb0318b5e9ed3dfdea5501a3260f3acea commit r15-430-gc4af8ebdb0318b5e9ed3dfdea5501a3260f3acea Author: Rainer Orth <r...@cebitec.uni-bielefeld.de> Date: Mon May 13 14:02:46 2024 +0200 testsuite: c++: Allow for std::printf in g++.dg/modules/stdio-1_a.H [PR98529] g++.dg/modules/stdio-1_a.H currently FAILs on Solaris: FAIL: g++.dg/modules/stdio-1_a.H -std=c++17 scan-lang-dump module "Depset:0 decl entity:[0-9]* function_decl:'::printf'" FAIL: g++.dg/modules/stdio-1_a.H -std=c++2a scan-lang-dump module "Depset:0 decl entity:[0-9]* function_decl:'::printf'" FAIL: g++.dg/modules/stdio-1_a.H -std=c++2b scan-lang-dump module "Depset:0 decl entity:[0-9]* function_decl:'::printf'" The problem is that the module file doesn't contain Depset:0 decl entity:95 function_decl:'::printf' as expected by the test, but Depset:0 decl entity:26 function_decl:'::std::printf' This happens because Solaris <stdio.h> declares printf in namespace std as allowed by C++11, Annex D, D.5. This patch allows for both forms. Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11, and x86_64-pc-linux-gnu. 2024-05-13 Rainer Orth <r...@cebitec.uni-bielefeld.de> gcc/testsuite: PR c++/98529 * g++.dg/modules/stdio-1_a.H (scan-lang-dump): Allow for ::std::printf.
