Update patch below/attached (the original one also didn't apply anymore after one of the others was committed). Jan gas/ 2005-02-11 Jan Beulich * config/tc-ia64.c (ia64_parse_name): Don't advance 'name' when parsing inN, locN, outN. Set 'idx' to offset register number starts at. Don't handle numbers with leading zeroes or beyond 95. Remove pointless cast. gas/testsuite/ 2005-02-11 Jan Beulich * gas/ia64/nostkreg.[ds]: New. * gas/ia64/ia64.exp: Run new test. --- /home/jbeulich/src/binutils/mainline/2005-02-11/gas/config/tc-ia64.c 2005-02-11 11:09:20.000000000 +0100 +++ 2005-02-11/gas/config/tc-ia64.c 2005-02-11 11:29:01.872465160 +0100 @@ -7482,7 +7482,6 @@ ia64_parse_name (name, e, nextcharP) { struct const_desc *cdesc; struct dynreg *dr = 0; - unsigned int regnum; unsigned int idx; struct symbol *sym; char *end; @@ -7588,13 +7587,14 @@ ia64_parse_name (name, e, nextcharP) } /* check for inN, locN, or outN: */ + idx = 0; switch (name[0]) { case 'i': if (name[1] == 'n' && ISDIGIT (name[2])) { dr = &md.in; - name += 2; + idx = 2; } break; @@ -7602,7 +7602,7 @@ ia64_parse_name (name, e, nextcharP) if (name[1] == 'o' && name[2] == 'c' && ISDIGIT (name[3])) { dr = &md.loc; - name += 3; + idx = 3; } break; @@ -7610,7 +7610,7 @@ ia64_parse_name (name, e, nextcharP) if (name[1] == 'u' && name[2] == 't' && ISDIGIT (name[3])) { dr = &md.out; - name += 3; + idx = 3; } break; @@ -7618,13 +7618,16 @@ ia64_parse_name (name, e, nextcharP) break; } - if (dr) + /* Ignore register numbers with leading zeroes, except zero itself. */ + if (dr && (name[idx] != '0' || name[idx + 1] == '\0')) { + unsigned long regnum; + /* The name is inN, locN, or outN; parse the register number. */ - regnum = strtoul (name, &end, 10); - if (end > name && *end == '\0') + regnum = strtoul (name + idx, &end, 10); + if (end > name + idx && *end == '\0' && regnum < 96) { - if ((unsigned) regnum >= dr->num_regs) + if (regnum >= dr->num_regs) { if (!dr->num_regs) as_bad ("No current frame"); --- /home/jbeulich/src/binutils/mainline/2005-02-11/gas/testsuite/gas/ia64/ia64.exp 2005-02-02 08:33:18.000000000 +0100 +++ 2005-02-11/gas/testsuite/gas/ia64/ia64.exp 2005-02-08 11:43:19.000000000 +0100 @@ -44,7 +44,8 @@ if [istarget "ia64-*"] then { run_dump_test "ldxmov-1" run_list_test "ldxmov-2" "" run_dump_test "ltoff22x-1" - + + run_dump_test "nostkreg" run_list_test "invalid-ar" "" run_dump_test "dependency-1" --- /home/jbeulich/src/binutils/mainline/2005-02-11/gas/testsuite/gas/ia64/nostkreg.d 1970-01-01 01:00:00.000000000 +0100 +++ 2005-02-11/gas/testsuite/gas/ia64/nostkreg.d 2005-02-04 15:02:33.000000000 +0100 @@ -0,0 +1,16 @@ +#objdump: -dr +#name: ia64 not stacked registers + +.*: +file format .* + +Disassembly of section \.text: + +0+000 <_start>: +[[:space:]]*[[:xdigit:]]+:[[:space:][:xdigit:]]+\[M[IM]I\][[:space:]]+mov[[:space:]]+r5=0 +[[:space:]]+0:[[:space:]]+IMM22[[:space:]]+in00 +[[:space:]]+1:[[:space:]]+IMM22[[:space:]]+loc96 +[[:space:]]*[[:xdigit:]]+:[[:space:][:xdigit:]]+mov[[:space:]]+r6=0 +[[:space:]]*[[:xdigit:]]+:[[:space:][:xdigit:]]+mov[[:space:]]+r7=r32 +[[:space:]]*[[:xdigit:]]+:[[:space:][:xdigit:]]+\[M[IM]B\][[:space:]]+mov[[:space:]]+r8=r34 +[[:space:]]*[[:xdigit:]]+:[[:space:][:xdigit:]]+mov[[:space:]]+r9=r36 +[[:space:]]*[[:xdigit:]]+:[[:space:][:xdigit:]]+br\.ret\.sptk\.few[[:space:]]+(b0|rp);; --- /home/jbeulich/src/binutils/mainline/2005-02-11/gas/testsuite/gas/ia64/nostkreg.s 1970-01-01 01:00:00.000000000 +0100 +++ 2005-02-11/gas/testsuite/gas/ia64/nostkreg.s 2005-02-04 14:47:29.000000000 +0100 @@ -0,0 +1,9 @@ +_start: + mov r5 = in00 + mov r6 = loc96 + .regstk 2, 6, 2, 8 + .rotr in0I[2], loc1L[2], out2O[2] + mov r7 = in0I[0] + mov r8 = loc1L[0] + mov r9 = out2O[0] + br.ret.sptk rp
