| * 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. | |
