Use #include "..." for our own headers, <...> for others Tracked down with an ugly, brittle and probably buggy Perl script. Also move includes converted to <...> up so they get included before ours where that's obviously okay.

tests/tcg/xtensa: support configurations w/o vecbase Configurations w/o vecbase may have vectors not grouped together and not in fixed order. They may not always be grouped into single output sections by assigning next offset to dot, as it may sometimes move dot backwards and sometimes they may even belong to different memory region. Don't group vectors into single output section. Instead put each vector into its own section ant put it at its default virtual address. Reserve 4KBytes from the default vectors base and put rest of the code and data starting from there. Mark vectors sections as executable, otherwise their contents is discarded. There may be as little as 16 bytes reserved for some vectors, load handler address into a0 and use ret.n to jump there to make vector code fit into this 16 byte space.

tests/tcg/xtensa: support configurations w/o vecbase Configurations w/o vecbase may have vectors not grouped together and not in fixed order. They may not always be grouped into single output sections by assigning next offset to dot, as it may sometimes move dot backwards and sometimes they may even belong to different memory region. Don't group vectors into single output section. Instead put each vector into its own section ant put it at its default virtual address. Reserve 4KBytes from the default vectors base and put rest of the code and data starting from there. Mark vectors sections as executable, otherwise their contents is discarded. There may be as little as 16 bytes reserved for some vectors, load handler address into a0 and use ret.n to jump there to make vector code fit into this 16 byte space.

tests/tcg/xtensa: move exception handlers to separate section Not all CPU configurations may have enough space for handler code between exception/interrupt vectors. Leave jumps to the handlers at the vectors, but move all handlers past the vectors area. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
