* The .MIPS.abiflags section must be defined with the FP ABI flags set
|
||
|
|
* to 'any' to be able to link with both old and new libraries.
|
||
|
|
* Newer toolchains are capable of automatically generating this, but we want
|
||
|
|
* to work with older toolchains as well. Therefore, we define the contents of
|
||
|
|
* this section here (under different names), and then genvdso will patch
|
||
|
|
* it to have the correct name and type.
|
||
|
|
*
|
||
|
|
* We base the .MIPS.abiflags section on preprocessor definitions rather than
|
||
|
|
* CONFIG_* because we need to match the particular ABI we are building the
|
||
|
|
* VDSO for.
|

|

|
* See https://dmz-portal.mips.com/wiki/MIPS_O32_ABI_-_FR0_and_FR1_Interlinking
|
