config/ppc: workaround GCC 11.3 internal error
Building DPDK with gcc 11.3.x for the power10 instruction set may generate the following error: ../drivers/mempool/cnxk/cnxk_mempool_ops.c during RTL pass: final ../drivers/mempool/cnxk/cnxk_mempool_ops.c: In function ‘cnxk_mempool_alloc’: ../drivers/mempool/cnxk/cnxk_mempool_ops.c:124:1: internal compiler error: output_operand: invalid expression as operand 124 | } | ^ Please submit a full bug report, with preprocessed source if appropriate. ... ninja: build stopped: subcommand failed. The same issue is not encountered when building with gcc 11.4 or later, where the compiler automatically adds the option "-mno-block-ops-vector-pair" when building for power10 which is intended as a code optimization and also effectively avoids the compiler bug displayed. Modify the meson.build file for ppc and manually set the flag when building for power10 with gcc less than 11.4.
