Hi all,
This series resolves two independent but related issues that were recently exposed by two LLVM changes.
https://github.com/llvm/llvm-project/commit/ec92d74a0ef89b9dd46aee6ec8aca6bf... exposes that '-no-pie' is not getting added to the linker flags with clang, resulting in building objects with '-fno-PIE' that are linked with '-pie', to which the linker rightfully errors with:
/usr/sbin/ld: init/main.o: relocation R_X86_64_32 against symbol `saved_command_line' can not be used when making a PIE object; recompile with -fPIE /usr/sbin/ld: failed to set dynamic section sizes: bad value
https://github.com/llvm/llvm-project/commit/4bf8a688956a759b7b6b8d94f42d25c1... adds '.ltext' (and '.ltext.*' with '-ffunction-sections') when using '-mcmodel=large' (which UML does), which causes a segmentation fault with modpost.
I have tested these patches with all supported versions of clang, noticing no regressions.
--- Nathan Chancellor (2): um: Fix adding '-no-pie' for clang modpost: Add '.ltext' and '.ltext.*' to TEXT_SECTIONS
