[PATCH] analyzer: consider empty ranges and zero byte accesses [PR106845]

Hi, see my patch below for a fix of pr106845. I decided to allow bit_ranges and byte_ranges to have a size of zero and rather only add an assertion to the functions that assume a non-zero size. That way is more elegant in the caller than restricting byte_range to only represent non-empty ranges.

Hi, Segher! I'd like to thank you from the bottom of my heart ! I was happy to see my name listed in the github repository as well. This will motivate me to do my best to commit more to GCC.. :) Best Regards, Takahashi Akari https://github.com/takahashi-akari GPG Key: 9DD8 F529 83A0 3182 D318 6

[PATCH] xtensa: constantsynth: Add new 3-insns synthesis pattern

This patch adds a new 3-instructions constant synthesis pattern: - A value that can fit into a signed 12-bit after a number of either bitwise left or right rotations: => "MOVI(.N) Ax, simm12" + "SSAI (1 ... 11) or (21 ... 31)" + "SRC Ax, Ax, Ax" gcc/ChangeLog: * config/xten
