From b21b22e0688fffcd43af44aa3b234c7a5a4cd954 Mon Sep 17 00:00:00 2001 From: Petr Sorfa Date: Fri, 11 Jan 2002 16:56:04 +0000 Subject: [PATCH] 1) Handling of the DW_AT_byte_size attribute when processing a DW_TAG_string_type (this is acceptable under the current DWARF 2.1/3.0 standard.) 2) In read_tag_string_type(), a fix for FORTRAN that propagates the first string length to all string types. This is important as FORTRAN strings are not delimited as in C/C++. 3) Handling of the DW_LANG_Fortran95. --- gdb/ChangeLog | 9 +++++++++ gdb/dwarf2read.c | 25 ++++++++++++++++++++++--- 2 files changed, 31 insertions(+), 3 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 3d1d2fa..b8ba9a4 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,12 @@ +2002-01-11 Petr Sorfa + + * MAINTAINERS (write-after-approval): Add myself. + * dwarf2read.c (read_tag_string_type): Handling of + DW_AT_byte_size. + (read_tag_string_type): FORTRAN fix to prevent propagation of + first string size. + (set_cu_language): Handling of DW_LANG_Fortran95 + 2002-01-11 Richard Earnshaw * armnbsd-nat.c (fetch_inferior_registers): Change inferior_pid -> diff --git a/gdb/dwarf2read.c b/gdb/dwarf2read.c index 28317f2..785acc2 100644 --- a/gdb/dwarf2read.c +++ b/gdb/dwarf2read.c @@ -2786,12 +2786,30 @@ read_tag_string_type (struct die_info *die, struct objfile *objfile) } else { - length = 1; + /* check for the DW_AT_byte_size attribute */ + attr = dwarf_attr (die, DW_AT_byte_size); + if (attr) + { + length = DW_UNSND (attr); + } + else + { + length = 1; + } } index_type = dwarf2_fundamental_type (objfile, FT_INTEGER); range_type = create_range_type (NULL, index_type, 1, length); - char_type = dwarf2_fundamental_type (objfile, FT_CHAR); - type = create_string_type (char_type, range_type); + if (cu_language == language_fortran) + { + /* Need to create a unique string type for bounds + information */ + type = create_string_type (0, range_type); + } + else + { + char_type = dwarf2_fundamental_type (objfile, FT_CHAR); + type = create_string_type (char_type, range_type); + } die->type = type; } @@ -3797,6 +3815,7 @@ set_cu_language (unsigned int lang) break; case DW_LANG_Fortran77: case DW_LANG_Fortran90: + case DW_LANG_Fortran95: cu_language = language_fortran; break; case DW_LANG_Mips_Assembler: -- 2.7.4
