The two new options are column-info and no-column-info. This patch implements the new options for gdb_compile. These options have been tested with patch 2 of 2 on PowerPC with the GCC and clang compilers. Please let me know if the patch is acceptable for mainline. Thanks. Carl ------------------------------------------------------------- Add gdb_compile options column-info and no-column-info This patch adds two new options to gdb_compile to specify if the compile should or should not generate the line table information. The options are supported on clang and gcc version 7 and newer. Patch has been tested on PowerPC with both gcc and clang. --- gdb/testsuite/lib/gdb.exp | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) diff --git a/gdb/testsuite/lib/gdb.exp b/gdb/testsuite/lib/gdb.exp index aed7e2d043c..e993fddf4c7 100644 --- a/gdb/testsuite/lib/gdb.exp +++ b/gdb/testsuite/lib/gdb.exp @@ -4794,6 +4794,8 @@ proc quote_for_host { args } { # debug information # - text_segment=addr: Tell the linker to place the text segment at ADDR. # - build-id: Ensure the final binary includes a build-id. +# - no-column-info: Disable generation of column table information. +# - column-info: Enable generation of column table information. # # And here are some of the not too obscure options understood by DejaGnu that # influence the compilation: @@ -5003,6 +5005,34 @@ proc gdb_compile {source dest type options} { } else { error "Don't know how to handle text_segment option." } + } elseif { $opt == "column-info" } { + if {[test_compiler_info {gcc-*}]} { + if {[test_compiler_info {gcc-[1-6]-*}]} { + error "gdb_compile option no-column-info not supported." + } + lappend new_options "additional_flags=-gcolumn-info" + + } elseif {[test_compiler_info {clang-*}]} { + lappend new_options "additional_flags=-gcolumn-info" + + } else { + error "Don't know how to handle gcolumn-info option." + } + + } elseif { $opt == "no-column-info" } { + if {[test_compiler_info {gcc-*}]} { + if {[test_compiler_info {gcc-[1-6]-*}]} { + error "gdb_compile option no-column-info not supported." + } + lappend new_options "additional_flags=-gno-column-info" + + } elseif {[test_compiler_info {clang-*}]} { + lappend new_options "additional_flags=-gno-column-info" + + } else { + error "Don't know how to handle gno-column-info option." + } + } else { lappend new_options $opt }
