Tom de Vries 22589c4996 [gdb/testsuite] Fix gdb.guile/scm-type.exp with gcc 4.8 ... With gcc 7.5.0, I get: ... (gdb) guile (print (type-range (field-type (type-field (value-type \ (value-dereference f)) "items"))))^M = (0 0)^M (gdb) PASS: gdb.guile/scm-type.exp: lang_cpp: test_range: \ on flexible array member: $cmd ... but with gcc 4.8.5, I get instead: ... (gdb) guile (print (type-range (field-type (type-field (value-type \ (value-dereference f)) "items"))))^M = (0 -1)^M (gdb) FAIL: gdb.guile/scm-type.exp: lang_cpp: test_range: \ on flexible array member: $cmd ... There's a difference in debug info. With gcc 4.8.5, we have: ... <2><224>: Abbrev Number: 15 (DW_TAG_member) <225> DW_AT_name : items <22b> DW_AT_type : <0x231> <1><231>: Abbrev Number: 4 (DW_TAG_array_type) <232> DW_AT_type : <0x105> <2><23a>: Abbrev Number: 16 (DW_TAG_subrange_type) <23b> DW_AT_type : <0x11a> <23f> DW_AT_upper_bound : 0xffffffffffffffff ... and with gcc 7.5.0, we have instead: ... <2><89f>: Abbrev Number: 12 (DW_TAG_member) <8a0> DW_AT_name : items <8a6> DW_AT_type : <0x8ac> <1><8ac>: Abbrev Number: 17 (DW_TAG_array_type) <8ad> DW_AT_type : <0x29d> <2><8b5>: Abbrev Number: 41 (DW_TAG_subrange_type) <2><8b6>: Abbrev Number: 0 ... As mentioned in commit 858c8f2c1b "gdb/testsuite: adjust gdb.python/flexible-array-member.exp expected pattern": ... Ideally, GDB would present a consistent and documented value for an array member declared with size 0, regardless of how the debug info looks like. ... As in gdb.python/flexible-array-member.exp, change the test to accept the two values. Tested on x86_64-linux.		2021-10-07 18:00:08 +02:00
