From 29deb4221d07d2c497183853e6023acb51d49be9 Mon Sep 17 00:00:00 2001 From: Carl Love Date: Tue, 2 Jan 2024 17:45:55 -0500 Subject: [PATCH] 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 | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) diff --git a/gdb/testsuite/lib/gdb.exp b/gdb/testsuite/lib/gdb.exp index eb8f6998b1e..9ac707be696 100644 --- a/gdb/testsuite/lib/gdb.exp +++ b/gdb/testsuite/lib/gdb.exp @@ -5150,6 +5150,8 @@ 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. +# - column-info/no-column-info: Enable/Disable generation of column table +# information. # # And here are some of the not too obscure options understood by DejaGnu that # influence the compilation: @@ -5359,6 +5361,38 @@ proc gdb_compile {source dest type options} { } else { error "Don't know how to handle text_segment option." } + } elseif { $opt == "column-info" } { + # If GCC or clang does not support column-info, compilation + # will fail and the usupported column-info option will be + # reported as such. + if {[test_compiler_info {gcc-*}]} { + lappend new_options "additional_flags=-gcolumn-info" + + } elseif {[test_compiler_info {clang-*}]} { + lappend new_options "additional_flags=-gcolumn-info" + + } else { + error "Option gcolumn-info not supported by compiler." + } + + } elseif { $opt == "no-column-info" } { + if {[test_compiler_info {gcc-*}]} { + if {[test_compiler_info {gcc-[1-6]-*}]} { + # In this case, don't add the compile line option and + # the result will be the same as using no-column-info + # on a version that supports the option. + warning "gdb_compile option no-column-info not supported, ignoring." + } else { + lappend new_options "additional_flags=-gno-column-info" + } + + } elseif {[test_compiler_info {clang-*}]} { + lappend new_options "additional_flags=-gno-column-info" + + } else { + error "Option gno-column-info not supported by compiler." + } + } else { lappend new_options $opt } -- 2.39.5
