compile: New 'compile print' It is planned the existing GDB command 'print' will be able to evaluate its expressions using the compiler. There will be some option to choose between the existing GDB evaluation and the compiler evaluation. But as an intermediate step this patch provides the expression printing feature as a new command. I can imagine it could be also called 'maintenance compile print' as in the future one should be able to use its functionality by the normal 'print' command. There was a discussion with Eli about the command name: https://sourceware.org/ml/gdb-patches/2015-03/msg00880.html As there were no other comments yet I haven't renamed it yet, before there is some confirmation about settlement on the final name. Support for the GDB '@' operator to create arrays has been submitted for GCC: [gcc patch] libcc1: '@' GDB array operator https://gcc.gnu.org/ml/gcc-patches/2015-03/msg01451.html gdb/ChangeLog 2015-05-16 Jan Kratochvil <jan.kratochvil@redhat.com> Phil Muldoon <pmuldoon@redhat.com> * NEWS (Changes since GDB 7.9): Add compile print. * compile/compile-c-support.c (add_code_header, add_code_footer) (c_compute_program): Add COMPILE_I_PRINT_ADDRESS_SCOPE and COMPILE_I_PRINT_VALUE_SCOPE. * compile/compile-internal.h (COMPILE_I_PRINT_OUT_ARG_TYPE) (COMPILE_I_PRINT_OUT_ARG, COMPILE_I_EXPR_VAL, COMPILE_I_EXPR_PTR_TYPE): New. * compile/compile-object-load.c: Include block.h.
