Subject: RFC: Add GNU_PROPERTY_UINT32_AND_XXX/GNU_PROPERTY_UINT32_OR_XXX
Date: Wed, 13 Jan 2021 09:06:46 -0800 [thread overview]
Message-ID: <CAMe9rOq1hJiTaen1bH7SpWCB0hz0T39g5YTiOD-sk9jzwZrt1g@mail.gmail.com> (raw)
1. GNU_PROPERTY_UINT32_AND_LO..GNU_PROPERTY_UINT32_AND_HI
#define GNU_PROPERTY_UINT32_AND_LO 0xb0000000
#define GNU_PROPERTY_UINT32_AND_HI 0xb0007fff
A bit in the output pr_data field is set only if it is set in all
relocatable input pr_data fields. If all bits in the the output
pr_data field are zero, this property should be removed from output.
If the bit is 1, all input relocatables have the feature. If the
bit is 0 or the property is missing, the info is unknown.
2. GNU_PROPERTY_UINT32_OR_LO..GNU_PROPERTY_UINT32_OR_HI
#define GNU_PROPERTY_UINT32_OR_LO 0xb0008000
#define GNU_PROPERTY_UINT32_OR_HI 0xb000ffff
A bit in the output pr_data field is set if it is set in any
relocatable input pr_data fields. If all bits in the the output
pr_data field are zero, this property should be removed from output.
If the bit is 1, some input relocatables have the feature. If the
bit is 0 or the property is missing, the info is unknown.
