- Unroll fast paths in put_varint and get_varint - Replace while capacity loop with branchless term_grow_cap in runs_reserve - Vectorize continuation ring rehash with slice memcpy in cont_push - Fast-check simple line runs using combined bitwise XOR-OR mask in evict_simple_run - Resume batch simple-run eviction on interrupted sweeps in evict_for - Eliminate unused page_rows and page_simple allocations (>320 KB heap saved) - Add zero-delta bypass in Fenwick tree set_count - Replace iterative capacity loop with branchless term_next_pow2_32 in hist_view_sync - Eliminate prefix-walk in term_hist_view_find_row by reusing Fenwick remainder - Simplify upward and downward viewport movement in term_hist_view_scroll
13 daysterm: move the term core to subprojects/termBerke Güzel
The core now builds, tests, and benchmarks alone, as a Meson subproject with no dependency on the main tree. - include/term/ holds term.h and the header-only unicode/. src/ holds the core and its private headers. The main tree gets only include/term through term_dep, so it cannot reach a private header. - The term tests, the term benchmarks, the Kitty parser suite, and tools/amalgamate.py and tools/generate_unicode.py move with it. The tests run as term:<name>. - The main build passes its -march (arch_flag) and b_ndebug to the subproject. A directory configured before this commit needs meson configure -Dterm:arch_flag=-march=... once. - The term tests compile with -UNDEBUG. They do work inside assert. - The subproject exports term_test_dep with term_api.h, for the main tree's render, thumbnail, color, and selection tests. - The Kitty bridge used struct vector2i and has not compiled since the public API redesign. It builds again. 2 of its 14 tests fail: REP after a tab, and a cursor report after a resize. - dirgraph.py drops the term and unicode layers. Its self-test uses pty. - The symbols test ignores the __odr_asan symbols that ASan adds. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
