Revert "Add support to debug libtcc code" - not fully developed experimental feature This reverts commit1fe3e3bff5. This reverts commit4768b11737. Revert "tests: add test for x86_64 xor REX prefix bug in load()" - AI generated nonsense test This reverts commitd5ecb52a71. Revert "tccpp.c: Improve integer constant overflow warning" - Too long and confusing messages and comments for feature with questionable benefit. This reverts commit085bdf8997. riscv64-link: - cleanup "pair pcrel lo relocations by hi address" Fromfada98b1cetccgen.c: - Simplify "Cast signed pointer offset to ptrdiff_t before performing arithmetic" From5ad52cc1edlibtcc.c: - Revert "tcc options: document behavior and clashes (no-op)" a bit more information than one would like to have I think. (why try to understand that comments plus the extra script if one can as well just read the code itself ;) From234e2dd2bftccdefs.h: - Revert "Move lib/va_list.c into include/tccdefs.h" Lets not fill tccdefs.h with too much inline code Also, -nostdlib -run is no longer supported Fromfa6a6bfbbdarm64-gen.c: - cleanup "Implement TOK_NEG for floats natively" Also, make it "no lvalue" in tccgen.c/x86-64-gen.c Fromc39eaf10cflib/lib-arm64.c: - cleanup "Remove libc dependency from lib-arm64" using unions is much faster than some made up memcpy() From8c61b91de8
