Tested on hppa64-hp-hpux11.11. Committed to trunk. Needed for patch to remove dynamic relocations from .eh_frame.
Dave --- Disable CFI directives on hppa*-*-hpux* We want to use difference expressions in the .eh_frame section for EH encoding but gas defines CFI_DIFF_EXPR_OK to 0. So, we need to disable generation of CFI directives on hppa*-*-hpux*. GCC will generate the difference expressions itself. 2026-07-28 John David Anglin <[email protected]> gcc/ChangeLog: * configure.ac: Set gcc_cv_as_cfi_directive to no on hppa*-*-hpux*. * configure: Regenerate. diff --git a/gcc/configure.ac b/gcc/configure.ac index 763b094d6cf..5d315a11591 100644 --- a/gcc/configure.ac +++ b/gcc/configure.ac @@ -3549,6 +3549,14 @@ gcc_GAS_CHECK_FEATURE([cfi directives], gcc_cv_as_cfi_directive,, .cfi_escape 1, 2, 3, 4, 5 .cfi_endproc], [case "$target" in + hppa*-*-hpux*) + # The HP dynamic linker relocates text and data separately, so + # differences between text and data don't work.
