--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Marc Poulhi?s <d...@gcc.gnu.org>: https://gcc.gnu.org/g:396db92d3aa7412dd7133563fecbc6237fa81c02 commit r14-5936-g396db92d3aa7412dd7133563fecbc6237fa81c02 Author: Simon Wright <si...@pushface.org> Date: Tue Nov 28 14:56:36 2023 +0100 Fix PR ada/111909 On Darwin, determine filesystem case sensitivity at runtime In gcc/ada/adaint.c(__gnat_get_file_names_case_sensitive), the current assumption for __APPLE__ is that file names are case-insensitive unless __arm__ or __arm64__ are defined, in which case file names are declared case-sensitive. The associated comment is "By default, we suppose filesystems aren't case sensitive on Windows and Darwin (but they are on arm-darwin)." This means that on aarch64-apple-darwin, file names are treated as case-sensitive, which is not the default case. The true default position is that macOS file systems are case-insensitive, iOS file systems are case-sensitive. Apple provide a header file <TargetConditionals.h> which permits a compile-time check for the compiler target (e.g. OSX vs IOS); if TARGET_OS_IOS is defined as 1, this is a build for iOS. 2023-11-22 Simon Wright <si...@pushface.org> gcc/ada/ PR ada/111909 * adaint.c (__gnat_get_file_names_case_sensitive): Split out the __APPLE__ check and remove the checks for __arm__, __arm64__. For Apple, file names are by default case-insensitive unless TARGET_OS_IOS is set. Signed-off-by: Simon Wright <si...@pushface.org>
