From: Jakub Jelinek Date: Fri, 4 Dec 2020 09:54:45 +0000 (+0100) Subject: dwarf: Add -gdwarf{32,64} options X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=65312dfc64744405326a9f4c243f1b4c8f21de1b;p=gcc.git dwarf: Add -gdwarf{32,64} options The following patch makes the choice between 32-bit and 64-bit DWARF formats selectable by command line switch, rather than being hardcoded through DWARF_OFFSET_SIZE macro. The options themselves don't turn on debug info themselves, so one needs to use -g -gdwarf64 or similar. 2020-12-04 Jakub Jelinek * common.opt (-gdwarf32, -gdwarf64): New options. * config/rs6000/rs6000.c (rs6000_option_override_internal): Default dwarf_offset_size to 8 if not overridden from the command line. * dwarf2out.c: Change all occurrences of DWARF_OFFSET_SIZE to dwarf_offset_size. * doc/invoke.texi (-gdwarf32, -gdwarf64): Document. --- diff --git a/gcc/common.opt b/gcc/common.opt index 582e2aa8774..6645539f5e5 100644 --- a/gcc/common.opt +++ b/gcc/common.opt @@ -3178,6 +3178,14 @@ gdwarf- Common Driver Joined UInteger Var(dwarf_version) Init(4) Negative(gstabs) Generate debug information in DWARF v2 (or later) format. +gdwarf32 +Common Driver Var(dwarf_offset_size,4) Init(4) RejectNegative +Use 32-bit DWARF format when emitting DWARF debug information. + +gdwarf64 +Common Driver Var(dwarf_offset_size,8) RejectNegative +Use 64-bit DWARF format when emitting DWARF debug information. + ggdb Common Driver JoinedOrMissing Generate debug information in default extended format. diff --git a/gcc/config/rs6000/rs6000.c b/gcc/config/rs6000/rs6000.c index c661f7a8a6c..d2666039ab1 100644 --- a/gcc/config/rs6000/rs6000.c +++ b/gcc/config/rs6000/rs6000.c @@ -3864,6 +3864,12 @@ rs6000_option_override_internal (bool global_init_p) if (TARGET_DEBUG_REG || TARGET_DEBUG_TARGET) rs6000_print_isa_options (stderr, 0, "before defaults", rs6000_isa_flags); +#ifdef XCOFF_DEBUGGING_INFO + /* For AIX default to 64-bit DWARF. */ + if (!global_options_set.x_dwarf_offset_size) + dwarf_offset_size = PTR_SIZE; +#endif + /* Handle explicit -mno-{altivec,vsx,power8-vector,power9-vector} and turn off all of the options that depend on those flags. */ ignore_masks = rs6000_disable_incompatible_switches (); diff --git a/gcc/doc/invoke.texi b/gcc/doc/invoke.texi index 38c4d6a865a..671b29702ea 100644 --- a/gcc/doc/invoke.texi +++ b/gcc/doc/invoke.texi @@ -453,7 +453,7 @@ Objective-C and Objective-C++ Dialects}. -gstabs -gstabs+ -gstrict-dwarf -gno-strict-dwarf @gol -gas-loc-support -gno-as-loc-support @gol -gas-locview-support -gno-as-locview-support @gol --gcolumn-info -gno-column-info @gol +-gcolumn-info -gno-column-info -gdwarf32 -gdwarf64 @gol -gstatement-frontiers -gno-statement-frontiers @gol -gvariable-location-views -gno-variable-location-views @gol -ginternal-reset-location-views -gno-internal-reset-location-views @gol @@ -9654,6 +9654,18 @@ information as possible into a separate output file with the extension debug information.
