- Issue #10089
-
- gcc/
- * expr.c (store_field): Avoid a direct store if the mode is larger
- than the size of the bit field.
- * stor-layout.c (layout_decl): If flag_strict_volatile_bitfields,
- treat non-volatile bit fields like volatile ones.
- * toplev.c (process_options): Disallow combination of
- -fstrict-volatile-bitfields and ABI versions less than 2.
- * config/arm/arm.c (arm_option_override): Don't enable
- flag_strict_volatile_bitfields if the ABI version is less than 2.
- * config/h8300/h8300.c (h8300_option_override): Likewise.
- * config/rx/rx.c (rx_option_override): Likewise.
- * config/m32c/m32c.c (m32c_option_override): Likewise.
- * config/sh/sh.c (sh_option_override): Likewise.
-
- gcc/testsuite/
- * gcc.target/arm/volatile-bitfields-4.c: New test.
- * c-c++-common/abi-bf.c: New test.
