It is a shame that the new feature only applies to .text . Data sections and other code sections should be reorderable as well. I believe tuning the semantics can make it more useful. lld's -z keep-text-section-prefix and --symbol-ordering-file=3D work the following way: * When -z keep-text-section-prefix is specified, .text.hot.* sections are placed into the output section .text.hot. .text.unlikely, .text.startup, etc are similar. Otherwise, all .text.* go to .text. * There is no fixed order among the text output sections. The first seen one wins. https://github.com/llvm/llvm-project/blob/main/lld/test/ELF/= text-section-prefix.s If the user add `asm(".section .text.hot,\"axR\",%progbits"); asm(".section .text.unlikely,\"axR\",%progbits");` to the crtbegin source file, the output section order can be fixed in a desired way, regardless of whether .text.startup/.text.hot appears first in application code. * Normally a wildcard pattern in an input section description (e.g. *(.text .text.*)) uses the input order. However, if --symbol-ordering-file=3D is specified, it overrides the order. https://github.com/llvm/llvm-project/blob/main/lld/test/ELF/symbol-ordering= -file.s Back to GNU ld, I wonder whether we can say, when config.text_section_ordering_file is present, drop all the existing rules (e.g. ${RELOCATING+*(.text.exit .text.exit.*)}), and keep just *(.text .text.*). Make the ordering file decide how the wildcard is ordered. > > > diff --git a/ld/testsuite/ld-scripts/start.s b/ld/testsuite/ld-script= s/start.s > > > new file mode 100644 > > > index
