Chris Zankel 78f3cdfa2a xtensa: Fix linker script to include .literal sections Fix resembles implementation from Marc Gauthier and Piet Denaly: In the Xtensa architecture, assembly generates literals which must always precede the code (the L32R instruction that loads them only uses negative PC-relative offsets). For any .text section, literals are placed in a corresponding .literal section. The linker script (vmlinux.lds) must place these in the correct order. It must also combine them, when the .text section can be larger than L32R's 256 kB range. For example, this doesn't work: (.literal) (.text) because L32R instructions at the end of .text can't reach the literals. The linker can solve this if they are combined in parentheses, like this: (.literal .text) because it is now allowed mix literals in .text to bring them in range. None of this is done by standard vmlinux.lds.h macros such as TEXT_TEXT and INIT_TEXT. To avoid replicating the logic of that header file, we instead post-process the generated linker script to convert (xxx.text) to (xxx.literal xxx.text) for the following text sections: .text .ref.text .init.text .exit.text .text.* using a sed script. To do this we must override the default rule for vmlinux.lds (see scripts/Makefile.build and the top-level Makefile) to insert this extra step.
