To enable running 32-bit binaries in compat mode on 64-bit kernels, support 4 KiB and 8 KiB page sizes for 32-bit, but only 8 KiB pages for 64-bit. The 64-bit toolchain defaults to 1 MiB page size support, so bump the page size range on 64-bit to that, disregarding Linux support. Note: We could fix the 64-bit page size at 8 KiB and XFAIL a future alignment test (currently the gaps test will fail because of the excess load segment alignment). --- sysdeps/sparc/sparc32/bits/pagesize.h | 2 ++ sysdeps/sparc/sparc64/bits/pagesize.h | 2 ++ 2 files changed, 4 insertions(+) create mode 100644 sysdeps/sparc/sparc32/bits/pagesize.h create mode 100644 sysdeps/sparc/sparc64/bits/pagesize.h diff --git a/sysdeps/sparc/sparc32/bits/pagesize.h b/sysdeps/sparc/sparc32/bits/pagesize.h new file mode 100644 index 0000000000..373d367b7b --- /dev/null +++ b/sysdeps/sparc/sparc32/bits/pagesize.h @@ -0,0 +1,2 @@ +#define __GLIBC_PAGE_SHIFT_MIN 12 +#define __GLIBC_PAGE_SHIFT_MAX 13 diff --git a/sysdeps/sparc/sparc64/bits/pagesize.h b/sysdeps/sparc/sparc64/bits/pagesize.h new file mode 100644 index 0000000000..aec8f97a10 --- /dev/null +++ b/sysdeps/sparc/sparc64/bits/pagesize.h @@ -0,0 +1,2 @@ +#define __GLIBC_PAGE_SHIFT_MIN 13 +#define __GLIBC_PAGE_SHIFT_MAX 20
