lib: zstd: Mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: lib/zstd/bitstream.h:261:30: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/zstd/bitstream.h:262:30: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/zstd/bitstream.h:263:30: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/zstd/bitstream.h:264:30: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/zstd/bitstream.h:265:30: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/zstd/compress.c:3183:16: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/zstd/decompress.c:1770:18: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/zstd/decompress.c:2376:15: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/zstd/decompress.c:2404:15: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/zstd/decompress.c:2435:16: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/zstd/huf_compress.c: In function ‘HUF_compress1X_usingCTable’: lib/zstd/huf_compress.c:535:5: warning: this statement may fall through [-Wimplicit-fallthrough=] if (sizeof((stream)->bitContainer) * 8 < HUF_TABLELOG_MAX * 4 + 7) \ ^ lib/zstd/huf_compress.c:558:54: note: in expansion of macro ‘HUF_FLUSHBITS_2’ case 3: HUF_encodeSymbol(&bitC, ip[n + 2], CTable); HUF_FLUSHBITS_2(&bitC); ^~~~~~~~~~~~~~~ lib/zstd/huf_compress.c:559:2: note: here case 2: HUF_encodeSymbol(&bitC, ip[n + 1], CTable); HUF_FLUSHBITS_1(&bitC); ^~~~ lib/zstd/huf_compress.c:531:5: warning: this statement may fall through [-Wimplicit-fallthrough=] if (sizeof((stream)->bitContainer) * 8 < HUF_TABLELOG_MAX * 2 + 7) \ ^ lib/zstd/huf_compress.c:559:54: note: in expansion of macro ‘HUF_FLUSHBITS_1’ case 2: HUF_encodeSymbol(&bitC, ip[n + 1], CTable); HUF_FLUSHBITS_1(&bitC); ^~~~~~~~~~~~~~~ lib/zstd/huf_compress.c:560:2: note: here case 1: HUF_encodeSymbol(&bitC, ip[n + 0], CTable); HUF_FLUSHBITS(&bitC); ^~~~ AR lib/zstd//built-in.a Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough.
