2019-02-08binutils: Add new GNU format mode to `size` utilityAndrew Burgess5-38/+145
The size tool currently defaults to berkeley format output. However, this output format has a weird quirk, read-only data is counted against the text sections, not the data sections. The code offers no real explanation for why this is, but I'm reluctant to change it for two reasons, first, I'm assuming it probably makes sense in some case that I'm not thinking of (maybe a target where sections are not marked executable, and so there's no distinction between read-only data and code), and second, the code has been this way for at least 20 years, I worry that changing things now might cause more confusion than it solves. This commit then introduces a new output format for the size tool, this new format displays the results in a similar manor to the berkeley format, but counts read-only data in the data column, and only executable sections are counted in the text column. Given that this is a brand new output format I've gone ahead and simplified things a little, while the berkeley format displays the total twice, once in decimal and once in hex, the new display format just displays the total in decimal. Of course, there's still the '--radix' option which can be used to display all the results in hexadecimal or octal. I've called the new format 'gnu', so '--format=gnu' or '-G' are used to access it. binutils/ChangeLog: * size.c (berkeley_format): Delete. (enum output_format): New enum. (selected_output_format): New variable. (usage): Update to mention GNU format. (main): Update to extract options, and select format as needed. Handle GNU format where needed.

2018-12-14elf: Add PT_GNU_PROPERTY segment typeH.J. Lu7-21/+26
Linkers group input note sections with the same name into one output note section with the same name. One output note section is placed in one PT_NOTE segment. New linkers merge all input .note.gnu.property sections into one output .note.gnu.property section with a single NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment. Since older linkers treat input .note.gnu.property section as a generic note section and just concatenate all input .note.gnu.property sections into one output .note.gnu.property section without merging them, we may see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which are invalid. GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such that linker sets the bit for non-relocatable outputs. But it isn't sufficient: 1. It doesn't cover generic properties. 2. When -mx86-used-note=yes is passed to x86 assembler, the GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED property in object file and older linkers generate invalid NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit set. I am proposing the following changes: 1. Add PT_GNU_PROPERTY segment type: # define PT_GNU_PROPERTY (PT_LOOS + 0x474e553) which covers .note.gnu.property section. 2.
