I don't know. Looking at the resulting linker script (and with your
suggestion):
.text (((0x00002000 - 0x00002000) + ((128 << 20))) - 0x00040000) : AT(((LOADADDR(.DoubleExceptionVector.text) + SIZEOF(.DoubleExceptionVector.text) + 4 -1)) & ~(4 -1)) { _text_start = ABSOLUTE(.); *(.literal .text) *(.text_version_string) *(.literal.* .text.* .stub) *(.gnu.warning .gnu.linkonce.literal.*) *(.gnu.linkonce.t.*.literal .gnu.linkonce.t.*)
*(.fini.literal) *(.fini) *(.gnu.version) _text_end = ABSOLUTE(.); }
So there's "literal" scattered everywhere. If it doesn't matter, it
reads more consistently to me to toss literal in one more time. But I
emailed around and we'll see if xtensa stays around, it's also our
oldest toolchain and virtually untouched since submission :(
