Dimitry Andric 0efce95397 chinese/c2t: fix "error: address of register variable requested" ... During an exp-run for llvm 13 (see bug 258209), it turned out that chinese/c2t fails to build with clang 13: cc -O2 -pipe -fstack-protector-strong -fno-strict-aliasing -DCHINDICT=\"/usr/local/share/chinese/gb/TONEPY.tit\" -c c2t.c c2t.c:99:3: error: address of register variable requested hz[2] = '\0'; ^~ c2t.c:107:7: error: address of register variable requested hz[0] = (char)eka; ^~ c2t.c:108:7: error: address of register variable requested hz[1] = (char)toka; ^~ c2t.c:113:8: error: address of register variable requested if (hz[0] != (*pipo)[i] || hz[1] != (*pipo)[i+1]) continue; ^~ c2t.c:113:31: error: address of register variable requested if (hz[0] != (*pipo)[i] || hz[1] != (*pipo)[i+1]) continue; ^~ c2t.c:133:36: error: address of register variable requested fprintf(miss_chars, "%c", hz[0]); ^~ c2t.c:134:30: error: address of register variable requested fprintf(miss_chars, "%c ", hz[1]); ^~ c2t.c:143:17: error: address of register variable requested printf("%c", hz[0]); ^~ c2t.c:144:18: error: address of register variable requested printf("%c ", hz[1]); ^~ 9 errors generated. As indicated, arrays shouldn't be register variables as they don't have addresses. In general, the register keyword is deprecated and should no longer be used. To fix this, use a command line flag to define "register" to empty. PR: 258465 Approved by: maintainer timeout (2 weeks) MFH: 2021Q4		2021-10-02 13:19:56 +02:00
