|
* 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 |
|
* for the .MIPS.abiflags section description. |
