I propose defining constants for all ELF dynamic flags (pertaining to DT_FLAGS_1). This will help, for example, determining whether an object is a position-independent executable (PIE).

The following constants would be added and defined (according to Table 15-10 in https://docs.oracle.com/en/operating-systems/solaris/oracle-solaris/11.4/linkers-libraries/dynamic-section.html):

DF_1_NOW
DF_1_GROUP
DF_1_NODELETE
DF_1_LOADFLTR
DF_1_INITFIRST
DF_1_NOOPEN
DF_1_ORIGIN
DF_1_DIRECT
DF_1_INTERPOSE
DF_1_NODEFLIB
DF_1_ENDFILTEE
DF_1_DISPRELDNE
DF_1_DISPRELPND
DF_1_NODIRECT
DF_1_EDITED
DF_1_SYMINTPOSE
DF_1_GLOBAUDIT
DF_1_SINGLETON
DF_1_STUB
DF_1_PIE
DF_1_KMOD
DF_1_WEAKFILTER

We generally permit new file format types and constants to be added without a formal proposal, as long as they follow the existing docs.

Thanks, that's good to know. I was following the instructions in https://go.dev/doc/contribute#testing, and all.bash was complaining because of the api check.

Add constants for all ELF dynamic flags (pertaining to DT_FLAGS_1). This will help, for example, determining whether an object is a position-independent executable (PIE). The constants are defined according to Table 15-10 in https://docs.oracle.com/en/operating-systems/solaris/oracle-solaris/11.4/linkers-libraries/dynamic-section.html.
