Subject: [PATCH v2 0/1] LoongArch: Add support for the third expression of .align for R_LARCH_ALIGN
Date: Fri, 22 Dec 2023 10:28:25 +0800 [thread overview]
Message-ID: <20231222022826.1318958-1-mengqinggang@loongson.cn> (raw)
If the symbol index is not zero, the addend is used to represent
the first and the third expressions of the .align.
The lowest 8 bits are used to represent the first expression.
Other bits are used to represent the third expression.
The addend of R_LARCH_ALIGN for ".align 5, ,4" is 0x405.
The addend of R_LARCH_ALIGN for ".balign 32, ,4" is 0x405.
Changes from v1:
Set the address of symbol in R_LARCH_ALIGN to zero.
