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.
